This reworks how emotes are cached in relation to their physical
location on disk. Functionally, they should be the same from the user
perspective but it sets up some stuff that will make it easier to add
emotes from various sources.
Added a limit to how long the title can be when set from the /playing
command. The default value is 50 if it is not in the settings file or
if the value in the settings is below zero.
