Fixing spectrum indexing and adding instrument name retrieval for correct geometry loading. This refs #1759.

Adding python algorithm that uses local sns findnexus python library. This will not work offsite. Fixes #1710.

Refs #1749: Fix logParser test. Reverted to old code but added a check in the event of a single value (return the value instead of 0).

Fix a bug when reading an ISIS SANS mask file containing a line to switch off transmission fitting. Fixes #1775

re #1772 - changes to script file for application of the TofCorrection algorithm in Indirect Energy Conversion routine based on a parameter in the instruments parameter file.

Refs #1749. Test failed for some reason, trying to see if I can get a more useful message. Unfortunately I do not have a windows machine on which to debug.

Refs #1722: Touching qtiplot in order to force a rebuild, because on the build server, qtiplot builds before the framework, which is a little silly.

Refs #1749 and #1722: Added IRectangularDetector and ParRectangularDetector in order to handle parametrized locations. I seem to be having trouble getting the values from the DAS logs, but the plotting works though.
