snglcoinc:  remove coincident_process_ids()
llwapp:  remove unused import
ligolw_cafe:  add local wrapper for get_coincident_segmentlistdict()
lalapps_power_pipe:  allow partial coincs

replace llwapp.get_coincident_segmentlistdict() with ligolw_cafe.get_coincident_segmentlistdict(), a wrapper that generalizes to coincs with <n participating instruments
cosmicstring.py:  (possibly) fix segmentlist construction

it's possible that the identification of segments to analyze for
coincidence was missing times when less than all instruments were on.
porting from llwapp.get_coincident_segmentlistdict() to
ligolw_cafe.get_coincident_segmentlistdict() should be sure to get them all
llwapp:  move get_coincident_segmentlistdict() to ligolw_cafe

all calling code now uses the wrapper in ligolw_cafe, so the version in llwapp is no longer required.  this moves the function to ligolw_cafe, and modifies it to do what the wrapper was affecting.
ligolw_sqlite:  edit a comment
pylal:  bump version to 0.3.0
dagfile:  fix broken error messages

forgot to enumerate the lines in the file so there's an undefined symbol error in each raise statement that this fixes.
dagfile:  add support for new-style rescue DAGs

this adds a .load_rescue() method to the DAG class that will parse a new-style rescue DAG and set the job states appropriately.  there is no support for writing a new-style rescue DAG at this time, but condor still supports the old style, with DONE on the JOB lines.
glue(1.44.1), Post ER3 release of glue for pegasus 4.2 transition, added new RFC Proxy support.
