.c 2 9 doesn't work about cardinal-cah

[johnmaguire]

OK, this was still #7. I thought I had fixed it, but while I reloaded the plugin, the plugin imports game.py, which doesn't reload because reload() isn't called on it and it's cached in sys.modules. I fixed this in a097afa by moving all of game.py into plugin.py, which I don't particularly like.

Looking at supybot plugins, it looks like they force the plugin to call reload() on any of its imports. This works well for second-order imports though it does mean plugin authors need to be aware of this limitation.

Another solution would be to somehow modify sys.modules to cause it to do a fresh load on all imports, but this probably has lots of dangerous side effects. In any case, that would need to be done inside Cardinal's core.

For now, I'm going to use the reload() trick.
