1) I made a number of changes to image saving. These include:

   - Overhauling the save window options in the GUI. The standard save and 
     advanced multi-window save tabs have been removed and replaced with an 
     aspect ratio and resolution section and a multi-window save section. The 
     aspect ratio, resolution and screen capture controls have been moved 
     into the aspect ratio and resolution section. The tiled and advanced 
     multi-window save controls have been moved into the multi-window save 
     section. The stereo control has been moved into the format options 
     section.
   - Modifying advanced multi-window image saving to initialize the background
     to white.
   - Modifying the viewer to take into account the save tiled and advanced
     multi-window save settings when setting the image width and height.

   These changes resolve #2330.

2) I added a QSixCharLineEdit class to QNarrowLineEdit.h.
