QMAKE_FRAMEWORK_BUNDLE_NAME and QMAKE_BUNDLE_EXTENSION don't support spaces.

Creating a framework bundle with spaces in the name is not possible.

QMAKE_FRAMEWORK_BUNDLE_NAME = "Qt Based Application"
QMAKE_BUNDLE_EXTENSION = .test extension

Current workaround is to use set a name without spaces and use QMAKE_POST_LINK to run a script file to rename the bundle and fix the dependencies.
