R143 – Added release plan

Also added a release plan sketching some most important things needed to be able to run an OpenSource project much more elemental than personal home hacks (such as my glossary checker, text editor and such private experimental stuff).

2013-04-25 update: note the discrepancy between the 0.0.1 R143 and the R130-R141 – Heavy refactoring 0.0.1.0, which was originally 0.1.0! I conventionally choose 0.0.X.R for alpha stages, where R is added in order to get in a revision.

R142 – Refactoring 5

Preparing the VM yet another time by refactoring in revision 142. Now the code is prepared for storage in short ints, which is going to be the storage format for the virtual machine. The storage of the literals is yet undetermined.
