change to not use isinstance() in determing types

- reload() of modules messed this up greatly, in certain cases.  Modules
  get re-executed when you reload(), which causes the classes to be
  redefined, meaning that the classes stored in the Meeting object are
  *not* any longer subclasses of items.*
- With the other fixes I did, this was only going to be a problem if
  supybot reloaded the MeetBot module during a meeting, however, it's best
  to plan for that anyway.
- I switch to comparing m.itemtype to a string value.  Not as elegant,
  but works for now.
