new `pragma experimental` grammar yields SyntaxError

Hello -

Just a quick note that the new pragma experimental grammar yields exceptions in the parser.

Example output:

isaac@localhost:~/Development/truffle$ ~/Programs/truffle/node_modules/truffle-core/cli.js test
SyntaxError: Error parsing /home/isaac/Development/truffle/contracts/Registry.sol: Expected "solidity", comment, end of line, or whitespace but "e" found. Line: 3, Column: 8

Example script:

pragma experimental SMTChecker;

contract Demo {}

I realize that this report is somewhat brief description (and that solidity-parser is to be transferred to the truffle organisation) -- will update this issue report once I've got time. Thanks for the amazing work!
