Instead of providing no-op CheckJsr/CheckJsl, plugins now declare which calls they support by defining interfaces on the plugin class. I added a CheckBrk call for code like Apple /// SOS calls, which use BRK as an OS call mechanism. The formatting doesn't work quite right yet because I've been treating BRK as a two-byte instruction. Hardly anything else does, and I think it's time I stopped (but not in this commit). Note: THIS BREAKS ALL PLUGINS that use the inline JSR/JSL feature, which is pretty much all of them.
