big update: moved stuff to roles, sudo root

* moved tasks before roles to role main.yml files
** role ymls in root dir only start role, nothing else
* removed group vars and moved default settings to role defaults
* group_vars/ dir can be used for local overrides now
* use sudo at include level: start as root, sudo to users as needed
* change to sudo root started: most (?) parts are run sudo root and can be
* started as any user => must be checked

fixes:
* fix logfile permissions for redmine
* adapt to new gem module behaviour: set user_install=no to use rvm dirs
* rvm installs packages now (?), so it must have sudo rights

other:

* gem returns version now, don't use complicated shell command anymore
* restart redmine instead of brutal nginx service restart
* avoid problems with plugins: remove test deps for redmine until ruby
  gets its stupid dependency management done...
