Issue 12 beta changes

So Issue 12 is in open beta now, and there's a ton of changes. Lots of quality-of-life improvements, many of which relate to chat messages. Unfortunately, those changes mean much of what HeroStats does has to be changed in order to work with I12.

By far the biggest change is how message channel is identified. Pre-I12, the channel type was hardcoded to a particular value, and each message was tagged with the appropriate channel type value. Now that's no longer the case. Messages are instead stored in the client memory with pseudo-HTML tags that set the message color and other attributes. This is great for the game client - it enables the linking you see in I12, and the ability to change the color of each channel on your tabs. But it's not so good for HeroStats, because there's now no good way to take a message and figure out which channel it came from. Those pseudo-HTML tags don't help, because they can be changed by the user at will.

So, we're going back to an approach that I tried once before - scanning each tab of the chat message window, rather than looking for individual channels. This can potentially give us better performance, but does require that the users have their chat tabs set up in certain ways. I'm working on a way to make this transparent to the user, or at the very least use the new I12 feature to load tab settings from a file to make it easy to set up.

This also means that we no longer know which channel a particular message belongs to. Previously the channel was used to 1) let people choose which channels that HeroStats would log and 2) filter out messages on channels that never contained any information needed for stats gathering. Both of those features will no longer be available with the new system.

I haven't had as much time as I'd like to work on this, so the new scanning system isn't completely ready for prime time just yet. I'm hoping to have it finished before Memorial Day, hopefully prior to I12 actually going live.
