Makes the code nicer, we use the ProFileReader to parse the mkspec.

Introduced struct DebuggerStartParameters to pass around
start parameters, removing the need for the engines to
access private members of DebuggerManager. Pass it
to DebuggerManager::startNewDebugger() and move
the GUI parts of that function into DebuggerPlugin,
making it possible to create the struct from command line
parameters. Introduce command line parsing with a few more
-enable-xx options. Introduce warning() to debugger panel
in the CDB engine.

On this occasion, clean out a few trailing whitespaces.

At the same time, fixed the order in the QuickOpen plugin to make sure
the RefreshInterval setting isn't immediately removed after saving it.

Also disabled debug output for settings database.

Also fixed the restoring of the refresh interval, which was broken due
to different keys being used for saving and restoring.

Mainly because DocumentStates should be moved there, because it can grow
quite large. Backward compatibility is kept.

Potential replacement for QSettings. This database will allow us to save
settings incrementially, removing most of the performance issues we're
having when our few megabytes of settings are being saved.

Not done in the form of a QSettings backend because it doesn't seem the
backends can do an incremental update of the settings.

Currently used by the QuickOpenPlugin for testing.

The dock widget visibility was not saved/restored correctly, and pulling
floating dock widgets back into the layout didn't remove the header
widget in case of locked mode.
Now we track visibility and floating state of dock widgets directly.

Do not trigger the whole debugger mechanism when Dumpers
crash on encountering uninitizialized variables. Temporarily
ignore the exceptions while in dumper call.

Handle functions with 0 variables correctly in the stack view.
Give names to unnamed formal parameters (causing WatchData
warnings). Ignore exception 06ba.

That is: Using the Run action, which fails due to build errors.
Using the Build action afterwards to rebuild.
This starts the executable.

Use correct path, display download link and notify that
settings take effect at next restart.

I need to test more cases, but this fixes it for newly created projects.

Check for x32 as well; pop up a message box on failure.

Added IExternalEditor which knows a kind and a mimetype.
Make EditorManager and ProjectExplorer "Open With" query
the interface and add the respective kinds.
