Older versions of Poco didn't have an AbstractConfiguration::remove member
so we had to fake it. This is no longer required as we need the newer
versions due to other bug fixes.

 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 VTP file saving simplified as files based on a checksum cannot be out of date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

All OSs should now go through the same procedure and only require the
pvplugins.directory to be set for the VSI to work.
Refs #7363

Before seeing how the bundling packaging worked out, I wanted to make sure
that running PV the old way still worked and introduced a number of fixes
along the way.

1) ParaView now returns 0 for success rather than 1

2) We need to explicitly put the PV_PLUGIN_PATH environment variable
through via the vtk system utilities as it will not be picked up
otherwise.

Why not ask them to cite both! refs #10759
