Giving MCServer a version number

[worktycho]

For an example have a look at Debian does.
Release is where stable code is.
However I think its probably better to have a branch between master and release. So master gets changes has they happen, and we have a second branch, testing, which holds the version we are stabilizing. Otherwise we have to stop merging features into master every so often or have stable builds be unstable at the beginning of each release cycle.
