Automatic update of the Visual Studio 2010 project files to Visual
Studio 2012

Allows parameters to be set from saved XML and changes the
parameterEditor buttons (currently for discrete parameters only) to
reflect which parameters are currently used by selected and
non-selected channels. This fixes a problem where the buttons would
always show what the last press was rather than the current values for
the active channels (e.g. If you changed the parameters on Channel 2,
and then switched to select only Channel 1, the GUI would incorrectly
indicate that the settings for Channel 2 were active). Additionally,
allows the user to see what parameter values are used for channels not
currently selected.

This ignores Emacs autosave files and any directory-local variable
files.

Ignoring these allows running cscope-indexer without git status
complaining.

That's an antipattern. Instead, add Source/Docs/* to .gitignore, and
let people build the docs themselves. This keeps them from getting out
of sync with the source tre and from cluttering up the diffs.

Whenever files are needed for recording, the RecordNode opens them. When
they are no longer necessary (either recording has stopped, or recording
of a particular channel has stopped), the RecordNode closes them.
