inspektor.vcs: Solve interactively existing branch on apply_patch

This patch adds couple of scenarios how to handle existing branch.
1) Abort - current solution
2) Delete - delete colliding branch and continue
3) Rename - rename colliding branch and continue
4) OldBase - rename colliding branch and apply patch to common base
5) NewBase - rename colliding branch, rebase it to the current master
             and continue
