Creator implemented Backtab similar to Eclipse and other editors,
now we do standard windows behavior.

When automatic insertion of brackets is disabled in the completion
settings, it is reasonable to expect the automatic matching of brackets
is also disabled.

Done with mae.

It now behaves less logical but closer to what vim does. Since
this is the main target group, the change is probably right.
In detail: Overwrite cursor no longer shows *what* will get overwritten,
but instead it simply indicates *that* the editor is in overwrite mode,
with a more or less fixed size (fixed when the font is truly monospace).

Especially in combination with block highlighting.

When drawing the background for an ifdefed-out block, expand
to the end of the visible viewport, even when scrolled
horizontally to the right.

We now use two cursors, with the first one being positioned at the
character before the find scope starts. This makes it possible
to extend the scope when typing at the beginning or the end of
it. This is more what the user expects. The effect is noticable
with find&replace of words at the beginning or end of the scope.

If the foreground color for the disabled text is different than the normal
text foreground, that's an indication that the user wants the disabled
block to be colored differently. If so, disable the syntax highlighting
and set uniform colors for the block.

If the foreground colors are identical apply full syntax highlighting in
the disabled block too. Some people want that.

The generated HTML is not the prettiest HTML in the universe, but it
does the job. When copying code from Qt Creator to Microsoft Office or
OpenOffice.org, the syntax highlighting is now preserved. The code also
pastes as preformatted text.

On some desktop environments, dragging and dropping a file gives us
the url to the file in multiple mime types, including text/plain. This
causes the url to be inserted as text by default.

Work around this issue by explicitly ignoring drop events for the text
editor when they also come with urls.
