- Fixed drawing the live indicator in the LCARS skin in case there are no devices.
- When checking for obsolete channels, those with an RID that is not 0 are now
ignored (suggested by Oliver Endriss).
+- The SDT is now only parsed *after* the NIT has been read, and it explicitly uses
+ the source value derived from the NIT. This should prevent new channels from being
+ created with the wrong source.
