Introduced new Creator-specific qmake variable QML_IMPORT_PATH that
lists the import paths required by the QmlJS engine.

Done-with: Alessandro Portale

Use the full path for folders to sort in the project tree.

For virtual folders ensure that the path ensures the sorting we want.

We create a .sis package per leaf project now, deploy all of them and
start the executable for the runconfiguration that was selected. This
does not cover all use cases, but works for development.

We now support renaming files. The version control system tries first to
rename, if that doesn't support or can't rename the file we do a normal
rename. (Note: git, hg, perforce > 2009.02 support renaming, cvs not.
(perforce untested)). We correctly notify all editors of the renamed
file and tell the project manager to rename the file in the project.

Note: Only the qt4projectmanager knows how to rename files.

Note: renaming folders, moving files to different folders, renaming
.pro/.pri files is not supported. Those things can be later added after
this has proven to work correctly in the simple case.

Also we don't do any actions based on the renaming like renaming
classes, changing include guards or #include lines.

This is a big change touching almost all of our .pro file parsing.
With this patch we only evaluate once exact for all needs and once
greedy for the filelist. That is the qt runconfigurations don't have own
evaluaters but reuse the project wide exact evaluation.

We reevaluate if the user changes the build directory, the qmake
buildconfiguration or the qmake arguments. That is if you open src.pro
(or projects.pro) of qt with a shadow build you still don't get all the
files, but after correcting the build directory, we reevaluate the .pro
files and find all files. So for a suitable definition of fixed, that
bug is now fixed.

We now get the exact defines of all .pro files instead of all defines for all
buildconfigurations. We still don't distinguish in which
.pro file a DEFINE is set. So the code model now knows about all the
defines set for the given configuration but not for which files it is
actually set. Also that includes all DEFINES set in .qmake.cache or the
mkspecs. This means all defines from .pro files should now work.

The intial loading is still synchronous. I haven't looked into it to
deeply, but it seems possible to make it also async.There are probably a
few issues which need to be solved fist.

Also due to the asynchronous nature of the code, the executable is
updated a few seconds after actually changing the build configuration

 * Do not use the BuildManager but have the qmakestep trigger
   the update via the target and project.

This code was (more or less) duplicated in 4 places.

there is no point in throwing away and re-recreating invariant data over
and over ...

shaves off ~15% of the load time of Qt 4.6.

Should fix a lot of corner cases, might introduce a few bugs.
Also rename functions/slots to be better named.

Generic Project Manager and CMake Project Manager are missing from this
patch.

...making use of the new code model features. Move code to
separate file. Make it possible to obtain path to generated
header file from project manager.

Note: I didn't fix all the connects and there are a few missing things.
This compiles, more work is coming.

The pointers can be used to distinguish BuildConfigurations

More API work.

Each project has it's own BuildConfiguarion * classes, they'll get a
decent type safe interface and the setValue/value stuff will be removed.

Enables users to change which buildsteps get run per buildconfiguration.
Some further tweaks are probably necessary. This is a rather big
change, though it should work. :)
