* use the correct BCCH channel type for nanoBTS
* remove old code
* ensure that the default BTS type really is BS-11
* document the '-t' commandline argument in the --help message

With this commit, I can get the nanoBTS 900 working with OML and RSL, register
to the network from phones.  Paging is not tested yet, and voice traffic handling
is completely missing..
