versioninfo: add commit + commit-date

[benlorenz]

commit and commit-date will only work when the package is used from a git clone. now works even with Pkg.jl clones using the cached repo.

add full option to enable all output and use it in the issue template.

full output looks like this:

(Oscar is using a git directory, GAP as well, for Polymake.jl I did ]add Polymake#master.

I had thought about mentioning earlier versions of Oscar.versioninfo that do not provide the full param, but they have only been there for such a short time that it doesn't make sense. At least in my opinion, feel free to adjust differently.
