Viewer ao improvements

See merge request alchemy/alchemy-next!5

This fixes association between the VISTA custom standing states and the viewer's own standing animation list:
The viewer AO will now load the animations present in the "Mode 1" preset - All standing animations, according to their manual - into the "Standing" animation list.
It will also avoid throwing misleading errors when loading the "Calm" and "Mode 2" states, as those are known, but not handled by the viewer AO.

Fix setting channel name for installer packages and add additional information to internal version info such as codename and commit sha
