CMake: Fails to build if dash in in project name

Steps to reproduce:

• create a Qt Quick project from template, use some project name with a dash
  (e.g. we use SampleApp-CMake as we create the same app for different build systems)
• build it

Current result:

• this fails due to issues with the Qt/CMake magic (qml_register_types code generated by qt_add_qml_module)

Expected result:

• QC should now which characters aren't allowed inside some of its used templates, so the templates should be filled corrected (e.g. illegal characters substituted by underscore?)
