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

Interesting point - I went with:
"Provide how many MP transactions have been parsed"
You think it's more useful to go with:
"Provide how many MP transactions have been parsed AND validated"

I still think perhaps the total parsed is more useful, but open to changing this is that's the general view :)
