Our "frame" concept very closely matches what the web specs call a
"browsing context", so let's rename it to that. :^)
The "main frame" becomes the "top-level browsing context",
and "sub-frames" are now "nested browsing contexts".
This patch updates the Page::keydown_event event handler to implement
crude Unicode support. It implements new method in EditEventHandler to
more easily handle deleting a single character after the cursor.
Furthermore, it makes use of the previously implemented methods to
increment and decrement the cursor position, which take into account
that Unicode codepoint may be multiple bytes wide.
This means it is now possible to mostly edit Unicode in editable DOM
nodes without any crashes. :^)

A C++ source file containing just
#include <LibFoo/Bar.h>
should always compile cleanly.
This patch adds missing header inclusions that could have caused weird error
messages if they were used in a different context. Also, this confused QtCreator.
