* kinda works
* exit crash fixed
* redline, remove some hardcoded
* removed cpu killer red line, and some fixes
* simplify #1
* seems ok. time to improve
* added hidden freq offset to receiver model, so wefax can be set to the "correct" freq without users needs to substract 300 hz
* badly implemented sync detection, and disabled it.
