Reworked the emote parsing to properly handle "wrapped" emotes. A
wrapped emote is one that is wrapped in colons or square braces (eg,
:Kappa: or [Kappa]). This allows emotes to be input without a space
between them, like is required with non-wrapped emotes.
A new configuration setting has been added to only allow parsing of
wrapped emotes: "WrappedEmotesOnly". This defaults to False as to not
break current configurations.
The emote autocompletion will only insert non-wrapped emotes. Setting
"WrappedEmotesOnly" configuration value to True will not change this.
Lastly, made the bare-word emote parsing a bit cleaner by removing a for
loop in favor of a map lookup with a check. This should in theory be
more efficient.
This change is in response to #111. The issue should not be considered
resolved until the autocompletion handles the new setting correctly.
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.
