Ladybird: Protect some application commands against non-Tab key windows

Browse source 
Currently, the only NSWindow type in the AppKit chrome is the Tab. Once
we have other window types (e.g. Inspector), commands which assume they
are used on a Tab will either crash or behave weirdly.

This changes the createNewTab: command to accept the tab from which the
new tab is created, rather than assuming that tab is the key window. So
if some JS on a page calls window.open() while a non-Tab window is key,
the new tab will be opened within the same tab group.

This also changes closeCurrentTab: to work on any key window. Regardless
of whether the key window is a Tab or some other window, pressing cmd+W
should just close that window.
