cccbe43056 LibJS: Use FlyString for identifiers 
This makes variable and property lookups a lot faster since comparing
two FlyStrings is O(1).

4f72f6b886 AK: Add FlyString, a simple flyweight string class 
FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.

When to use FlyString:

- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings

When not to use FlyString:

- For strings that don't need either of the above features
- For strings that are likely to be unique

d0629d0a8c Shell: More general tilde expansion 
Now expanding a tilde isn't hardcoded to just work for `cd`. It is instead
expanded while processing shell arguments. Autocompletion still doesn't
work, but this is definitely an improvement over the last iteration.

1ef3d4af69 Shell: Use starts_with() in expand_parameters 
This reads a little nicer, and makes us care less about an empty String

d806dfe801 Shell: Use size_t for SH_DEBUG vector iteration 
We missed this when switching to size_t for vector sizing as this
code is not normally compiled.

ec6e55cfc6 LibGUI: Don't spam WindowServer with SetWindowOverrideCursor messages 
Remember the override cursor in GUI::Window and avoid sending a message
to WindowServer when possible.

This removes a lot of synchronous IPC between Browser and WindowServer,
which noticeably improves DOM event responsiveness. :^)

fd5a3b3c39 LibGfx: Parse "rgb(r,g,b)" style color strings 
This parser is not very lenient, but it does the basic job. :^)

e2a38f3aba LibWeb: Add a naive implementation of setInterval() 
This implementation leaks a Core::Timer whenever you call setInterval()
so it will definitely need some improvements, but it does kinda work!

7c48c3c8e1 LibJS: Parse "if" statements 
This patch implements basic parsing of "if" statements. We don't yet
support parsing "else", so I added a FIXME about that.

4dde36844b LibWeb: Add a DOM Event class (instead of events being simple strings) 
This patch adds the Event base class, along with a MouseEvent subclass.
We now dispatch MouseEvent objects for mousedown, mouseup and mousemove
and these objects have the .offsetX and .offsetY properties.

Both of those properties are hard-coded at the moment. This will be
fixed in the next patch. :^)

b196665131 LibWeb: Dispatch "mouseup" event

mousedown happened.

324b92fd06 LibJS: Virtualize access to an Object's own properties 
Object now has virtual get_own_property() and put_own_property() member
functions that can be overridden to provide custom behavior.

We use these virtuals to move Array-specific access behavior to Array.

2a7dbac0c5 LibJS: Include the cell size in HeapBlock mmap names

00feef8642 LibJS: Some optimizations for ObjectExpression 
- move() the property map when constructing ObjectExpression instead of
  making a copy.
- Use key+value iterators to traverse the property map in the execute()
  and dump() functions.

6c3afca686 LibJS: Round cell sizes up to a multiple of 16 bytes

memory usage.)

bceabd7c4b LibJS: Add ArrayPrototype and implement Array.prototype.push() 
This function is ultimately supposed to be generic and allow any |this|
that has a length property, but for now it only works on our own Array
object type.

8f7d4f67a4 LibJS: Support reading/writing elements in an Array via Object get/put 
I'm not completely thrilled about Object::get() and Object::put() doing
special-case stuff for arrays, and we should probably come up with a
better abstraction for it.

But at least it works for now, which is really nice. :^)

a3d2e07446 LibJS: Parse computed MemberExpressions 
MemberExpression comes in two flavors:

non-computed: a.b

We can now parse both of the types. :^)

0891f860f7 LibWeb: Add CSS property 'border' 
This makes it possible to write shorter CSS. Instead of writing
.foo {
        border-width: 3px;
        border-style: solid;
        border-color: blue;
}
it is now possible to write
.foo {
        border: 3px solid blue;
}
while the order of values is irrelevant.
Currently only the basic values are supported. More values should be
added in the future.

Three more value specific parse functions were added:
parse_line_width, parse_color, and parse_line_style

Additionally a few test cases were added to borders.html.

4eef3e5a09 AK: Add StringBuilder::join() for joining collections with a separator 
This patch adds a generic StringBuilder::join(separator, collection):

    Vector<String> strings = { "well", "hello", "friends" };
    StringBuilder builder;
    builder.join("+ ", strings);
    builder.to_string(); // "well + hello + friends"
