Delete obsolete files

I removed files I decided not to keep..
Init script might had been handy, but I want this to be more or less
universal instead of targeting to specific distribution.
More file deletion or renaming..

Or renaming.. I decided that it's easier to rename project to
opengalax2 instead of keeping original name, this way, these both can
co-exist on same system..
Update Readme

I updated Readme to be more specific about this fork..
Update Makefile

Makefile defines now version number, optional extraversion and some
other things.
update to configfile.c

This fork no longer uses serio or calibration and has some new changes.
Update functions.c

Minor changes + get rid of serio stuff..
update 10-opengalax2.conf

renaming mostly..
75_opengalax2

some renaming..
opengalax.c -> opengalax2.c + changes

Rename + changes I made..
opengalax.h -> opengalax2.h + changes

Rename + some minor changes..
