Work towards a seperate panel fo rcamera views and sample positioning
Issue746: checking the SGM beamline status when startup the SGM beamline
configuration
remove the usage of this pointer
Altered:
- Uncommented code inside of AMCrosshairOverlayVideoWidget that never
updated the crosshair coordinates.  The code was there and worked
immediately after being uncommented.

@davidChevrier, it looks like you commented out this code, was there a
reason for that?  If there was we can revert this change and leave
@epengr to cry with his crosshairs.
rename the getter function to match the 'Acquaman Coding Converntions'
Added:
IDEASSampleCameraPanel
and required UI elements for sample positioning and sample slits

Modified:
Moved camera view from persistent bar to IDEASSampleCameraPanel
Added: new icons for slit controls
reduce the size of the spacer for the button (from 450 to 400) so that
the grid layout won't adjust due to showing the button
merge master
ADDED:
PVs for sample and jj slit motors to IDEAS beamline class
passed these new controls to the GUI already added to the sample camera
view and persistent bar.
cleanup
Removed old unuse variables, wifgets and methods
Modeified:
Tweaked available step sizes for sample stage controls
Changed SGMSSAApplication to be a standalone widget rather than an appController. User testing seems to indicate it's working.
Fixed macro protection so that it builds properly with enabled mobility.

Pull Request - Issue #661 - IDEAS Sample/Camera interface

I've built this with mobility both enabled and disabled. Everything seems to be good.
Updated the addPane() call to use the version from the Issue661.

Pull Request for Issue757

I quickly updated the addPane() call to look the same as the #661 branch. Everything else checks out. I looked at this on the SGM, and it doesn't appear to be drawing the crosshair at all. I'm guessing that one of the myriad of changes I made since I commented this out did the job. If it shows up again, I'll take care of it then.
