Add an optional workspace with a detector table which will be used rather than the instrument geometry. The table is changing according to http://trac.mantidproject.org/mantid/ticket/9879.

Added optional property for detector pars.

Just added declaration in init() method to pass
in a TableWorkspace containing detector parameters.

Added logic to check for L1.

Added code to see if an L1 column is there in
the detector pars workspace.
Added unit test for with/without L1

As this is causing some subtle problems with the current usage of ConvertUnits - which could be due to these changes or just the way a couple of tests are written.

But to be safe, I am going to create a new algorithm ConvertUnitsUsingDetectorTable() under ticket http://trac.mantidproject.org/mantid/ticket/10748.

Closing this now as we are just going to use a separate algorithm for now and probably need to look more seriously at ConvertUnits() in the future.
