Only three triggers will be processed per message. (I should create a
registry entry to customize this.)
Messages that are addressed at a specific user that exists in the channel will
have that user's name prepended to the factoid output.
Factoid triggers that are referenced from within messages will not produce
error messages if the factoid is not found.
Factoids that have an $arg or $nick special variable will not be triggered as
a reference.
Factoids that have the `noembed` meta-data value set to a true value will not
be invoked as a reference.
Allows changing of bot configuration values without needing to restart
bot instance or needing to edit pbot.pl script.
Registry will initially be populated with default values from pbot.pl,
but if a registry file exists then the registry values will take
precedence over the pbot.pl values. For instance, if you regset the
bot trigger to '%' then the trigger will be '%' even if pbot.pl has '!'
or something else explicitly set.
Some registry items can have trigger hooks associated with them. For
instance, the irc->botnick registry entry has a change_botnick_trigger
associated with it which changes the IRC nick on the server when a new
value is set via regset/regadd.
Tons of other fixes and improvements throughout.
