Allow release versions such as `v1.2.3` and `release-1.2.3` (as well as other patterns recognized by composer)

Ref: #35 (comment)

Should this be something that is dealt with in nikolaposa/version?

[Ocramius]

@ntzm yeah

[ntzm]

I opened an issue here: nikolaposa/version#12, looks like it won't be until 3.0 that it's considered

[ciaranmcnulty]

This is pretty important, AFAIK v1.2.3 was not only supported it was encouraged by composer, at least at one stage

[Ocramius]

Talked with @nikolaposa in person about this, and it will likely happen when he has time and willpower (PHP Serbia aftermath first)

[nikolaposa]

Support for v1.2.3 has already been implemented in https://github.com/nikolaposa/version/releases/tag/3.0.0 (15: Relaxed version parsing). I'll consider adding support for release- prefix for 3.1.0.

btw Are there any other prefixes besides v and release that would be worth considering?

[Ocramius]

Maybe @alcohol can answer that

[ntzm]

Looking through the composer source, seems it's just release- and v

[nikolaposa]

I mean, if I'm going to introduce that change, I would like it to be something that is not only Composer-specific, but more general, hence the question.

[alcohol]

Composer does not strictly follow semver formatting. If you look at https://github.com/composer/semver (specifically, the tests) you'll see it is very similar but there are a few deviations for legacy reasons. I think the v prefix is the only prefix we support. The release- prefix is not supported btw, but it is stripped for legacy reasons AFAIK.
