some fixes

* getChannelID has now no RID at the and if it is =0. The reason is
that LSTE returns the list of epgs without RID if it is 0. So the match
of the getChanneldID of a DVBChannel and an EPGEntry was not possible.
*  accept 910 as 
C (0, 12, 13, 14, 23, 25, 34, 35, 45, 56, 67, 78, 89, 910) Code rate high priority
D (0, 12, 13, 14, 23, 25, 34, 35, 45, 56, 67, 78, 89, 910) Code rate low priority
