It's now possible to specify a validation function for config
items.
Use that to validate line_height:
```
; ./target/debug/wezterm --config line_height=-1
08:41:10.576 ERROR wezterm > Error converting lua value from overrides to Config struct: Error processing Config::line_height: Illegal value -1 for line_height; it must be positive and greater than zero!; terminating
```

We don't really know which of the on-screen matches the user was
looking at when they selected the text, but assume that the one
nearest the bottom of the viewport is the one they want to select,
rather than the one closest to the top.

When evaluating an assignment expression like `foo = "bar"` the result
of the expression is nil and we'd print nil on the next line,
which often startles me as I'm used to other languages where the
result of such an expression is the rvalue that was just assigned.
Let's just suppress nil when it is the result of an evaluation
in the repl for a cleaner look.
Moved the gradient function into the color module, but kept an alias
under the old name.
Gradients now return color objects.
Converting colors to string now uses rgba format when alpha is not 100%.
Otherwise we can block the gui waiting for eg: a freshly opened firefox to
terminate.

That fear was realized but now resolved!

wezterm.color.parse() returns a color object that can be assigned in the
wezterm color config, and that can be used to adjust hue, saturation and
lightness, as well as calculate harmonizing colors (complements, triads,
squares) from the RGB/HSL color wheel.
I've been holding off from using UserData wrappers around things
because it is awkward to match them up with the To/FromDynamic
conversion.
This commit aims to help with that by implicitly calling the
tostring metamethod (if present) on a userdata both when printing
(so the values look reasonable in the repl) and when mapping a lua
value to a dynamic value.
Provided that the end type is try_from=String this will allow
the userdata value to be assigned as table value.
The intent is that when set, it changes defaults to something
more suitable for distributions.
I've also added a readme for distro maintainers.

This commit expands the toml file definition to include
metadata for the origin url, author and name.
A new sync utility fills out that metadata when it pulls from the iterm2
color schemes repo.
The utility also pulls down the scheme data json maintained by
the Gogh project: https://gogh-co.github.io/Gogh/ and converts
it to wezterm's format.
About 50% of Gogh overlaps with iterm2; we take the iterm2 versions
of those schemes by default because the iterm2 data has more info
about things like cursor and selection colors.
The sync utility is responsible for compiling the de-duplicated
set of scheme data into a form that is used by wezterm and its
docs.
Since applying the maximized state is async, we hadn't fully applied
it before we got to the startup logic that resizes the window to fit
the initial terminal size.
This adds a final check to see if we are resizable before we try
to apply that size, and skips it.

I've wanted to avoid checking in all the screenshot pics as the png
files change every time I run the generation script, and it bloats
the repo over time.
This commit changes the doc generation step to use the asciinema
web player with the equivalent contents.
Really, it's only a smallish step to go from this to just emitting
the html directly in the doc pages, but I think I might use
the player for some examples in the future.
I think this is still a fine step for now in any case.
While comparing this with the existing screenshots, I noticed the
the Alabaster screen shot png has the wrong color for its rightmost
column: there's an issue in wezterm in parsing the dynamic color
escapes that causes it to pick up the wrong color.
Loading the scheme by name has the correct color and matches
how it is shown as of this commit.
Not sure why this only really showed up with Wayland, because the
issue was that the computed tab bar height ended up being 1 or 2
pixels shorter than the area we had allotted.
This commit resolves it by forcing the height to match, and
then aligning the content to the bottom of that region to avoid
having an undesirable line under the tab.

When using the win32 keyboard encoding, the delete and backspace keys
were encoded with the wrong character codes compared to the native
terminal. This caused subtle issues in multiple applications.
This change brings the encoding in line with the native terminal.
