Version format option

[nathanboktae]

I'd be nice to specify the version format - maybe not the full version format, but alot of repositories don't use the leading v but just the semver number. Perhaps even autodetect this based on the previous tags? This is what I have in one of my repos

~/github/cherrytree-for-knockout fc2636b|master ✔
10:51AM ᐅ git tag
0.0.1
0.0.2
0.0.3
0.0.4
v0.0.5

Would be nice to have it consistent.

Great tool BTW.
