Added new blocks written in python for new experimental gsm receiver.
...
FCCH burst tagger is element of hierarchical block - FCCH detector that adds tags after every detected FCCH burst. The value of each tag is a frequency offset estimate.
SCH detector waits for tags from FCCH detector which are used to find SCH burst position. It is unfinished.

Replaced nasty hack for training sequences 6 and 7 with a condition depending on the first symbol of training sequences. It's still a little bit of a hack because I don't know why exactly those starting points have to be used.
