Allow elements to be given custom names with [] syntax. ie, gstreamer-launch disksrc[mysrc] ! ...

Browse source 
Original commit message from CVS:
Allow elements to be given custom names with [] syntax.

ie, gstreamer-launch disksrc[mysrc] ! ...
makes a disksrc element named mysrc, rather than disksrc0

Suggestion: don't name things with names with numbers at the end, or they
may conflict with names allocated automatically.
