Remove stray tab characters which crept in over time
Compiler warning fixes from Brian Knittel
CAPS11 now runs on SimH. The key bug was in the reset routine.  Change by Bob Supnik.

Thanks to Ian Hammond, Lou Ernst, Malcolm Macloud, and Jack Rubin,

In addition, I've added the CAPS11 bootstrap into the emulator module, so no more toggle-in required.

Lou Ernst reported that RT11 V5 does not work with the TA11, even on real hardware. The simulated TA11 does work under RT11 V4; it's included in the stock FB monitor.

One anomaly with RT11 V4 - after writing files to CT0: and then doing a DIRECTORY, all the files lengths are 0. The files are there. I can type them and DIFF them against their source.

Remove unused definitions
Add sim_video and VAX QVSS (VCB01) Monochrome Video Board from Matt Burke
Fix incorrect definition descriptions in comments
Added logic to suggest libSDL might help with simulators what can use it when it isn't available.
Fixed reporting of libSDL availability in simulatoes which will never need it.
Added reporting of the QVSS window focus release key when Video Windows is created
Cleanup Visual Studio Build issues
Fixed the Visual Studio build of simulators which statically link against libSDL.
Add descriptions to the QVSS register declarations
Added "HELP SET dev" and "HELP SHOW dev" as eqivalent to "HELP dev SET" and "HELP dev SHOW" respectively.
Renamed Visual Studio Projects VAX610, VAX620 and VAX630 to be consistent with the target names produced by those project builds.

This allows the projects to be migrated into Visual Studio 2010 and Visual Studio 2012 and produce consistent behavior.
Cleanup of Visual Studio VAX project to properly convert to newer Visual Studio versions.
ignore emacs scratch and backup
Access violation if invalid command entered to remote console
