I decided to rename the c1gcv model to be c1als.  This is in an ongoing effort to rename all the ALS stuff as ALS, and get rid of the various GC{V,X,Y} named stuff.

Most of what was in the c1gcv model was already in a subsystem with and ALS top names, but there were a couple of channels that were outside of that that had funky names, namely the "GCV_GREEN" channels.  This fixes that, and make things more consistent and simple.

Of course this required a bunch of other little changes:

• rename model in userapps svn
• target/fb/master had to be modified to point to the new chans/daq/C1ALS.ini channel file and gds/param/tpchn_c1als.par testpoint file
• rename RFM channels appropriately, and fix in receiver models (c1scx, c1scy, c1mcs)
• move custom medm screens in userapps svn (isc/c1/medm/c1als), and link to it at medm/c1als/master
• moved old medm/c1gcv directory into a subdirectory of medm/c1als
• update all medm screens that point to c1gcv stuff (mostly just ALS screens)

The above has been done.  Still todo:

• FIX SCRIPTS!  There are almost certainly scripts that point to GC{V,X,Y} channels.  Those will have to be fixed as we come across them.
• Fix the c1sc{x,y}/master/C1SC{X,Y}_GC{X,Y}_SLOW.adl screens.  I need to figure out a more consistent place for those screens.
• Fix the C1ALS_COMPACT screen
• ???
