Please consider stabilising version taggimg convention

[kloczek]

To allow easiest way to automatically package this project please:

1. do not use underscores in in version because none of the packaging systems allow use underscores in version string. Please use just dots
2. drop all prefixes. like PSM2, IFS_RELEASE, or psm2.

fit auto generated tar balls from tags automatically adds to base directory name repo name as prefix so you don't need to use anything than just plan version with dots as separator.
