Sendmany invalid json for gridcoin!

[grctest]

When you generate a sendmany transaction it won't work in the gridcoin client.

I've reduced the addresses from 1000 to 250, it's still producing the error.

Perhaps it needs reduced even further?

Successful sendmany: http://www.gridresearchcorp.com/gridcoin/?transaction_detail&txid=8640b477ea16bb7c0a65b293aa2b219b6647c2edad872d5baac09ce6b0bdd504 Perhaps the max is ~ 100??
