support git clones

[AladW]

AUR4 added the ability to clone AUR packages via git. This allows amongst others to easily view maintainer changes in the pkgbuild. Right now trizen only supports the old tar interface.

The support for git clones is ready for testing.

Thanks, for me files are retrieved correctly on trizen -S. A question, is there a particular reason you're only fetching the latest commit (i.e., git log only displays one entry) ?

[trizen]

Thanks for the suggestion. There is no particular reason, other than a potential speed improvement for packages with many commits.

However, this is now configurable with the git_clone_depth config-option. By default, the value is 0, which means no limit.

Thanks!
