The LexicalPath instance methods dirname(), basename(), title() and
extension() will be changed to return StringView const& in a further
commit. Due to this, users creating temporary LexicalPath objects just
to call one of those getters will recieve a StringView const& pointing
to a possible freed buffer.
To avoid this, static methods for those APIs have been added, which will
return a String by value to avoid those problems. All cases where
temporary LexicalPath objects have been used as described above haven
been changed to use the static APIs.
Previously, copying a file to a directory, like this:
```cp README.md Desktop```
correctly copied it to Desktop/README.md, but would fail if the
source was also a directory, for example:
```cp -R Documents Desktop```
Now, that correctly copies it to Desktop/Documents, as you would
expect. :^)
