We previously allowed fully white and yellow colors as the
base color for our interface. This does not work with our
icons or other interface elements. Instead I now constrain
the selectable colors within a certain range of saturation
and brightness. This still leaves the user in control but
will prevent the common case where the user selects an
overly saturated color from the color picker and ends up
with an unusable or extremely ugly panel.

Do this for the fakevim plugin as well, which uses
a slightly modified version for its settings.

Those who do not like it can get the old behavior back by
setting the action to Ctrl+W in the shortcut settings.

I added a new focus rect for combo boxes
with manhattan style. To reduce the visual
impact I follow the same policy we use on
windows where we do not show the focus rect
unless it is called upon by tabfocus.

Do not add file watchers on editors with temporary files (VCS
diff/commit. etc). Add a flag to FileManager::addFile() specifying
if one wants a watcher.

Slightly increased the font size. Added a bit
more shadow and tweaked the progress bar.

Now lets get some feedback. :)

Moved Qt Designer to open from Design Mode. Also, Design mode is now global,
and created in coreplugin. Other plugins can register themselves to it.

The actualPixmapSize is different
from the resulting pixmap when using
svg icons. This seems to be a bug
in Qt, but using the resulting pixmap
is safe for now.

This is a cosmetic fix for the sidebar.
The highlight contrast is too high now that
the background is darker.

* Disable close button when there is no editor active
* Hide lock button when there is no editor active
* Hide the info bar when the editor is closed and no editors are left

This removes the extra line at the bottom of the window on the mac.
This also decreases the contrast of shadows and highlights a bit.

Introduce multithread-locking to Core::MimeDatabase as it is
invoked from the indexer thread to sort apart headers and sources.
Add a convenience to operate on a sequence to avoid locking for each
file.

We need to kill the fadeins before fading out.
Otherwise we might get into weird states.

I added a zerotimer to make the sidebar emit
currentChanged only after it has been updated as
pressed.

Killed the divider lines for improved aestetics
Made the hover a bit more subtle

* I have simplified and animated the tool buttons a bit.
* The panel has been replaced by a very basic clean panel.
* The tool buttons have been animated.

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.
