* Renamed aardvark_include.pri to aardvarkroot_includepath.pri and removed
  DEPENDPATH from file.
+ Added include_core.pri to simplify internal linking with Aardvark Core.
+ Split qaard_include.pri into qaard_qmakeglobal.pri and
  qaardroot_includepath.pri.
* Improved qmake project file consistency.
* All qmake project files now *= instead of += to ensure only unique additions
  are made. Except for CONFIG += ....
* Renamed header guards so project and subproject names are present to avoid
  unwanted collisions.
* Qbs files now use [abc] wildcards when useful.
