Gilles Dubuc 95dcc971b0 Reduce number of RL modules in MultimediaViewer
Having many modules makes the startup module in the head
unnecessarily longer. Things should only be in their own
module if they're going to be loaded on demand on their
own or are a shared dependency of separate modules that
are.

This change brings down the amount of modules declared by
Media Viewer from 53 to 8. The ones that remain are
mostly things loaded on demand.
