Bump version to 666

I decided to stop marking version numbers to correspond with Franco's builds.
Instead of that I'll name it simply version 666. I merge changes continualy
and very often there are new changes, that not belong to actual version number.
For example actual version 151 has already changes that belongs to version 152.
So I think, that version 666 will be better solution.
