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.
