Collect User templates for everyone to use

Basically this describes the process of generating a pull-request on github. For further question, please google as there are lots of tutorials.

• fork this git repository
• clone the fork to your computer
• checkout a new branch
• make your own template in TeXstudio with File/Make Template
• copy the generated files from .config/texstudio/templates/user (OSX/Linux) or %appdata%\texstudio\templates\user (win) to your cloned repository. Please use subfolder to sort like university for university templates. The names need to be meaningful for a global audience.
• Multi-file templates need to be generated manually, see manual and example template_Book.(json/png/zip)
• push the branch to your fork.
• On github activate "make pull request" or similar
