Satellites plug-in does not update some TLEs

It seems that at least a part of the problem is that some satellite identifiers have been changed in Celestrak's TLE lists. For example, AO-27 is listed as "EYESAT-1 (AO-27)" in http://celestrak.com/NORAD/elements/amateur.txt

NOAA have suffixes to their names (single characters in square brackets) without an apparent meaning. It is possible that this makes them unrecognisable to the plug-in.

I'm going to try and fix what I can.

OK, I have committed a fix to the main branch as revision 4756:
http://bazaar.launchpad.net/~stellarium/stellarium/trunk/revision/4756

In all cases, the problem was that an entry for a given satellite designation was missing from the source TLE lists, so that satellites couldn't be updated. For NOAA and IRIDIUM satellites this was caused by a faulty regular expression that was supposed to strip the "[*]" suffix from the name, but didn't do it. For amateur satellites, the source list used updated designations that no longer matched the ones in the list packaged with the plug-in.

I've modified the code to warn in the console/log file when the designation of some satellite can't be found in the update lists. A better solution would be to mark somehow in the interface those satellites that are not being updated for some reason (e.g. they have been defined by the user or are missing from the TLE lists). I will create a Blueprint for that.
