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.
The nick field is now optional and Getopt::Long is used to accept targeted
options for channel/history, allowing recalls by text/channel for any nick
which is useful when you know what text the message contained but not who
said it.
Added MessageHistory.pm and MessageHistory_SQLite.pm. May eventually port
and add MessageHistory_Hashtable.pm as was done with Quotegrabs, but this is
not particularly high on the todo list.
Antiflood.pm has been updated to use the new MessageHistory API.
The `recall` command has been moved from Quotegrabs into MessageHistory. It
also now has the ability to ignore messages containing the recall command
itself, for improved usability.
Likewise, the `grab` command will now ignore previous `grab` commands when
grabbing by regex in order to prevent accidentally grabbing previous grab
attempts.
The `join` and `part` commands have been improved to accept multiple channels,
and `part` will use the current channel if none is provided.
Two quotegrabs_db backends are now availble:
* Quotegrabs_Hashtable.pm: the original hashtable implementation
* Quotegrabs_SQLite.pm: the new SQLite implementation
Quotegrabs_SQLite.pm is now the default quotegrabs_db backend.
This was done to reduce the memory footprint of the bot by not needing to
keep the entire quotegrabs table in memory any longer.
A similiar change will be coming soon to the Factoids table as well as the
MessageHistory table.
This allows the more natural "replace 'a' with 'b' and 'c' with 'd'" syntax
rather than the previous syntax of "replace 'a' with 'b' and replace 'c' with 'd'"
