Make cuteproject more reusable

[mxklb]

Actually when someone want's to use cuteproject as a starting point for its own Qt5/C++ development its somehow complicated to do this. What needs to be done is renaming a lot of files and configurations, so that personal libs and app names are adjusted according to ones needs. This process shall be analysed to be automated.

Ideas are:

• there could be a config file (yml) containing meta data (project name, app name, gh-user, creds ..)
• there could be another repo containing cuteproject as a sub-module (to implement this issue)

Ideally there would be one single configure script (bash?) to prepare cuteproject for re-usage.

Additionally a documentation how to reuse cuteproject is missing and shall be also developed.
