this replaces the ever-repeating idiom block/save/unblock with a single
call.

Make sure none of the VCS systems claims it does support any
VCS operation while unconfigured. This stops the specific
VCS from showing up in wizards, etc. till they can actually
be used.

Do not offer to commit in the dialog opened when closing the
commit editor when the commit is not containing all the required
information.

Clean icore.h.

Rename "Reset..." back to "Undo Uncommitted Changes..." to be more
in line with git gui as well as the file-based operations.

String update as suggested by Leena.

Also introduce a indirection, modes have now types, edit and debug have
the same type, and editors do have a prefered type of modes instead of a
prefered mode.

That fixes the bug that if the prefered qml editing mode was set to
design, then in switching between qml editors would
- in Edit Mode: stay in edit mode
- in Debug Mode: switch to debug mode

The function always switched to Edit Mode, which was the cause for
several bugs. Since openEditor() already does switch to the right mode,
the function is not really needed.

The following actions now respect the prefered mode of the editor:
"f file"-locator
The Open Documents list
Editor history navigation

Modify CodePaster::fetch to do a mimetype detection on the
content, create a filename with the matching extension and
open that file.
This gives correct syntax highlighting  and makes "Save as"
more convenient. Keep the file around and delete on exit.

Modify patch mimetype with some content detection (higher priority
than C++).

Add a "current patch file" to the VCSBasePlugin::State. Add "Apply
patch" to git with whitespace fix.

Static leaks, but causes noise in valgrind output. :)

Create actions with convenient factory functions, do enabling per

in the same fashion as "Clean repository".

Present user with a checkable list of files to be cleaned (add reusable
dialog to VCSBase module).

And port the Qt4ProjectManager to use that API for synchronization
between editors and the .pro file tree.
