Fix typo in path of location of htdocs directory for SWATCH cell framework package
Following the makefile reorganisation of issue #11 (closed) , the SWATCH cell's polymer elements are installed under /opt/xdaq/htdocs/swatch/cell/framework
rather than the path that was previously used /opt/xdaq/htdocs/swatchcell/framework
(one fewer /
). But the cell still looks for the files in the same location as before
I'm not sure how this bug wasn't spotted , it must have crept in a last minute change since the most recent testing of the GUI.
