Parse Solidity Code into Spider Monkey API compliant AST

#UPDATE All changes have now been merged into solidity-parser (thanks to axic and tcoulter). I'll continue to maintain this repo until all reported issues have been fixed and once those changes are merged into solidity-parser, this repo's maintenance will be discontinued. (And solidity-parser shall be flawless by then ;) )

This is a (much more) refined version of solidity-parser. I've fixed a lot of bugs (see below) and added features as per solidity grammar spec (but obviously its not perfect a.t.m.). I plan to maintain it long-term =)

#List of bugs in solidity-parser (as of this writing)

• No 'name' field in StructDeclaration - this means we never get to know the name of the struct from the StructDeclaration Node object. (I made a PR for this but no response even after 2 weeks :()

• IsStatement malfunctioning - When using inheritance with Contract or Library, the syntax is:

contract Car is Vehicle, Engine {
        //definition
}

Solidity parser doesn't parse the 'is' section properly. the is Array's first object is fine (vehicle), but subsequent element is just a comma, not another object for Engine.

• Exponentiation operator (double asterisk) not being parsed by solidity parser

• A statement like uint x = 2 days; doesn't get parsed. It gives error at start of 'days'. (though SP parses the other tokens: "2 wei / 2 szabo / 2 finny, etc.", "days" is a valid suffix too but doesn't have support.

• Parse of var (x) = 100; failing because x is surrounded by brackets (which is legal in solidity).

All these bugs have been fixed in solparse! If you find a bug or a missing feature in this parser, please open up an issue :)
