Function selector is incorrect if there's a comment in the function signature definition

[mds1]

Steps to reproduce:

1. See this function has an inline comment
2. Run "List function signatures" for this file
3. Notice how it outputs 1137c1f8 => sendToken(address,address,uint256,bytes32,//) when it should output b9bfabe1 => sendToken(address,address,uint256,bytes32,bytes32)

Function linked above:

function sendToken(
    address _receiver,
    address _tokenAddr,
    uint256 _amount,
    bytes32 _pkx, // ephemeral public key x coordinate
    bytes32 _ciphertext
) external payable {
   ...
}

@mds1,

fixed it for the upcoming v0.1.1. let me know if you need it earlier and I can probably provide you an alpha.

the function signature extraction is super hacky and I do not expect that a lot of people are using it. if it turns out it is actually being used I might refactor the lexical extraction and actually use the AST.

cheers

PS: v0.1.1 will take a couple more weeks for testing.
