Large diff fixing projector tests

- Update some comments
- Some PJLink code fixes/restructuring
- Restructure some projector tests for proper mocking
- Fix manager.py and pjlink.py for changes to constants.py
- Fix test_projector_pjlink_routing.py for proper mocking and restructuring
- Renamed test_process_command_invalid to test_get_data_unknown_command
- Added test to verify assigned E_*/S_* codes are in STATUS_CODE and STATUS_MSG
- Added missing status/error codes to STATUS_MSG
- Added error checks to process_inpt
- Deleted unneeded test(s)
- More assert cleanups
- Merge trunk to fix conflicts

Updates to constants.py include:
    - Reordered dictionaries and lists into alphabetical order
    - Added PJLINK_ERST_LIST
    - Added S_NETWORK_IDLE code (for future)
    - Added PJLINK_STATUS list
    - Move S_QSOCKET_STATUS to QSOCKET_STATE
    - Move STATUS_STRING to STATUS_CODE
    - Move PJLINK_CLASS, PJLINK_SUFFIX, and PJLINK_PREFIX from pjlink.py to constants.py
    - Change CONNECTION_ERRORS from a dictionary to a list
    - Change QSOCKET_STATE to map QAbstractSocket.state() to local status codes
    - Merge ERROR_MSG with STATUS_MSG
    - Merge ERROR_STRING into STATUS_CODE
    - Clean out unused portion of PJLINK_ERST_STATUS
    - Clean out unused portion of PJLINK_POWR_STATUS
    - Clean out unused portion of QSOCKET_STATUS

[Tim Bentley (trb143)]

Some questions and old style asserts remain!

review: Needs Fixing

[Tim Bentley (trb143)]

Looks good and my issues have been resolved,
Unable to test code!

[Raoul Snyman (raoul-snyman)]

Actually, I'm getting a conflict in trunk, can you just merge from trunk and resolve that conflict please?
