in addition to being a convenient unload plugin, load plugin, this also
uses importlib.reload() to kick the interpreter to reload changed code
inside the plugin's package, if the user requests to reload the entire
package. this seems safe so far
(famous last words)
get rid of is_admin(), instead check for django permissions. a couple
things were using is_admin(), so now there's an example of the
permission adding and usage, as those were ported
sets up the foreign key and changes how is_admin() works, though it will
be going away pretty soon, i just need to do this migration in parts so
as to not confuse django too much
this allows plugins to register methods that can be called over XML-RPC
the old bot used this interface behind apache for a web service, but i
think in this version it will only be for django -> ircbot, and django
will have a rest API for other things
some ircds don't lead to a welcome signal, so our attempts to set the
nickmask there may never happen. guess at one first, in the event that
_on_welcome() never fires
for convenience, pass a list of events to add_global_regex_handler if
you want to have multiple things fire the same handler. common case is
pubmsg and privmsg
so initial tests suggest this is working well, but it's not exactly the
clearest code, so let's call this a rough proof of concept of recursion
in the bot
undecided if i'll bother to bring recursion back, but if it works out,
provide this method to either reply or give text to the thing recursing.
either way this is a bit clearer than using privmsg() directly, usually
a lot of stuff in here around support for loading plugins from arbitrary
files. plugins have a basic amount of initialization and then hook into
the core IRC event system
it makes sense to have modules respond to regexes, so there's some
handler stuff for that --- it was the most popular way to do stuff in
the old version of the bot
we need to check that people trying to load plugins are admins, so
there's some stuff for that, too
the expectation is that many features from here are happen in plugins,
rather than modifying the core bot
