When IPropertyManager::getValue fails to assign the property to the
specified type, a runtime_error is raised. Changed the error messages in
all (specific) cases to specify exactly what type it was expecting,
i.e. (const) shared_ptr<X> not just X or const X.

I've shortened ExperimentInfo::loadInstrumentInfoNexus a lot.

Preserves the expected path within the Nexus file
Refs #12656

The instrument_source attribute was removed and so the code hit an
error when trying to load the parameter map. As the instrument_source
is no longer used anywhere there is no point in trying to load it from
older files.

 1. Change the filename reported for nexus files if xml contained within
 1. Stop saving the filename to nexus processed files
 1. removed some unused includes

Still to do:
 1. cache SHA1 checksum if needed
 1. Manually test
 1. update documentation
 1. investigate this error:

re #11818

 1. IDS mangling used for checksum is now inst name + sha1 of xml
 1.1. sha1 is computed after converitng to linux line endings and trim
 1. VTP file names changes to be same filename as IDS mangling
 1. VTP save directory moved to appdata/mantidproject/instrument/geometryCache
 1. VTP file saving simplified as files based on a checksum cannot be out of date
 1. unit tests updated to account for this
 1. unused methods removed from IDFObject
 1. InstrumentDefinitionParser changed to initialise during constructor
 1. XML parsing changed to lazy load rather than during initialisation.

Still to do:
 1. cache SHA1 checksum if needed
 1. Change the filename reported for nexus files
 1. Manually test
 1. Stop saving the filename to nexus files
 1. update documentation

re #11818

and added processing to IDF processing algorithm.

The method is most often called in a loop so floods the log messages.
Refs #10470

and removed header references in .cpp files where this class not used

Change the behaviour of LoadIDFFromNexus and before doing this,
as part of trying to ensure I wasn't broking something, updated
various code comments related to loading of xml files

swap contents of new map with contents of old map instead.
