modules/rtv: add basic log_channels= setting
This introduces a boolean style log_channels= setting for enabling logging of channel settings on channel switch. It might be nice to change this to accept stdout/stderr/fdnum as the setting instead of always directing at stderr. This also doesn't capture the seed state so it's not exactly logging everything needed to reproduce wholly what is being shown. Some compositions depend more on rand than others, so it matters at varying degrees. It'd be nice for settings syntax to have some global syntax supported where a seed can always be embedded to be loaded. Introducing such things as global settings to the settings syntax is a pending TODO item... right now the only way to load seed state is at startup passed to main as --seed=. That's not gonna cut it long-term. This is an easy big step in the right direction though. Trying to make sense of what's on-screen from the truncated captions is impossible. Even if the captions wrapped the settings, it would be tricky to catch the settings without recording the output or screenshotting. This also immediately makes me wonder about the voting system for rtv where we log settings of favorites... then roll those into playlists.
