Add alerting and getinfo_MP

Please see notes here guys http://pastie.org/pastes/9733526/text?key=luz9fdv1whtvfhn1sjvckg

Before merging can we grab an hour to build this and run over how it works/test it out.

Thanks

A method of CMPTxList.. hm. I'm not sure, if this is the best place for it. `int CMPTxList::getMPTransactionCountTotal()` makes sense, because it's sort of general and related to Mastercoin transactions. Setting an alert not so much. Sorry, but no suggestion for an alternative.
