Fixed tests outside NeXus/DataHandling that relied on loading data
Had to add Nexus as a link dependency for various package Test targets - don't know why!
refs #2822

Added a setFacility()
refs #2760

Lower-case first letter of instruments and scripts directories. All our installers did this anyway and this will mean less manipulation of the properties file is needed. Re #2753.

Re-insert hack back as this seems to break lots of things.  The problem is being caused by relying on NOT finding the instrument definition and loading the info from the RAW files instead.  We should fix this, if people need to load from the RAW file they should do it explicitly. refs #1522

Remove ugly hack to get long instrument names in getInstrumentFilename(). Make sure we set the facility in the tests. Modify ConvertUnitsTest to account for fixed bug in correctly determining instrument long name for MARI.  refs #1522 & #2730

Put header parameters into workspace instead of instr. descr. (since it can change from file to file) Re #2725

Fixes #2726. The first line of the GSAS file should not have a comment, removed it. WinPlotr package is happy now.

Remove ugly hack to look for long instrument names.  Just use the Facility/Instrument in the ConfigService.  refs #1522
