re #11818

 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:

ctest -C Debug -J 4 -R LoadEventNexusTest -V

Refs #3984 Took the wiki description from every algorithm's wiki page and placed it in a comment in the CPP file (instead of the header file).

Continue obsession with const: ExperimentInfo(MatrixWorkspace)::getInstrument now returns a const instrument. Re #1944.

Eradicate IInstrument. Instrument's the one to talk to now (it was the only descendent class anyway). Re #2041.

Refs #2572: Added an initDocs() for all algorithms that sets the summary string to display in the dialog, as well as the wiki summary for possible later auto-wiki-fication of documentation.

Refs #2572: Ran into issue with un-escaped characters that my compiler did not catch. Commented out all optional messages until I can fix it.

Removed check for the executable name from the ConfigService. It now either uses the path pointed to by MANTIDPATH or the executable's directory if the former is not set. Also renamed a couple of functions relating to this so that it is clearer what their return values point. Re #2256
