Fixed an issue that Gil/Steven found with catalytic activities
spanning more than one line.  The script was treating
each line as individual reactions.  Since reactions
are delimited by a period '.' this patch stitches
multi-line CAs back together while keeping
multiple reactions (delimited by a period) separate.

Also switched to using the 'dbxrefprop type' cv instead of the
'property type' cv.
