Refactor language groovy to groovy_osgi during template creation

[Steffengreiner]

Feature request

During the library creation process in the selection of the primary language, Qube offers the language options java and groovy. The groovy library generated will conform to the OSGI standard.
However during the creation of a portlet with Qube, this can be selected via the groovy_osgi option during the primary language selection.

Describe the solution you'd like

Refactor the groovy option in the qube library creation process during the primary language selection into groovy_osgi. Alternatively provide it as a seperate option.
(However this would mean that the groovy option would allow for the creation of libraries outside of the OSGI setting)
Another solution would be to remove the groovy language option during portlet selection and adapt all qube created projects entirely to the OSGI standard.
