New release version format

Right now, PocketMine version strings follow this pattern: `(Alpha|Beta|Final)_([0-9]+)(|\.[0-9]+)(|dev)` + build number

Since in 1.4 a new development -> beta -> stable release process was introduced, the stage at the front (Alpha, Beta or Final) is not needed anymore. This only confuses people (oh, a beta build of an Alpha version!).

These changes are backwards compatible, and only affected internal PocketMine services (crash archive, build creation, homepage) that have been already upgraded.

Due to the nature of this change, a vote will be held. These changes were discussed on the team channel, and they liked the idea.
