Verision numbering changed

I finally decided not using year number as MediaCoder’s version number any more, as this will force me to change the it every year, which I feel is a pressure on me. I switched back to the traditional and continuous version numbering scheme of AA.BB.CC.BUILD. Current major version number of MediaCoder is 0.8.12 which is equilivant to former 2011-R12.

I am planning for and working on some new features, including better image overlaying feature, better paralell tasks handling and improving distributive transcoding. Next major version will be MediaCoder 0.9.
