Run git as a cmd.exe subprocess as a workaround. In the long term
we should look into enabling QProcess to properly handle .bat and
.cmd files.

core Find dialog and the "old" minibuffer based search.

A hot fix for the recent regression that 'n' and 'N' do not work and
the positioning of the cursor after the search is wrong.

Common things like :wq, :x, and :qa didn't work - now they do.

Creator already has a find box that works fairly well, so there
is no need for a mini-buffer mode for searching.  This change makes
FakeVim activate the standard find box when the user hits '/' or '?'.

Note: right now both '/' and '?' do forward searching by default
because the Creator find box lacks a "find backwards by default" mode.
This can be added later to the find box if considered useful.

When an example is selected, help and the project are opened
in a split view. We try to read the xml file provided for
QtDemo to extract details about the examples provided. Will
try all available Qts, starting with the default version. Will
fail gracefully (provide a message and disable controls) if
examples or demos cannot be found. Will work if help is not
found, but show an error.

Which nicely adds the occurrances to the search output window for
navigation.

Details:
I softened it ut to make it significantly less
distracting.

The setting, which terminal, to start an application in debug mode from, was ignored, since the QSetting was just not set.

After selecting a template in the NewFileDialog (Strg+N), a BaseFileWizard is started with an unusable BackButton.
This change removes the Button on first wizardpage.

Details:
I removed the beveled nokia font and redesigned the "tab bar"
from scratch. Should look a bit more shiny now. I'm aware of
the 'Q' going below the baseline but I think we can live with
it for now..

Do not check for existence of the binary, breaks on Windows
due to .exe (and potentially paths). Use waitForStarted().
On this occasion, kill on timeout in case of password prompts.

Now in Qt proper.

Manage Sessions replaces "Restore last session" (which can be done by clicking
the "(last session)" session anyway. Also, added a "Create New Project" button.
Ensured that the welcome screen is only as high as needed (will orient on the
amount of items in the contained treewidgets). Scrolling is still last resort.

The line would only get a reduced indent when the user actually typed
the }, but not when typing the {, even though the line should still be
unindented because of the } at the start.

Previously this code worked fine because lines didn't used to get
automatically reindented for anything else than the first character.

It broke indentation for global scope operator, and when that was fixed
it broke for the class initializer lists. I'm not sure how to fix that
at the moment, so better have it not do anything rather than being in
the way.
