Solidity <0.4.20 creates incorrect contracts output when are file paths with colon in them; could wrapper repair this?

Filing this issue based on discussion in #555. Currently[0] Truffle repairs this (see this Truffle PR for more info), but over on #555 @cameel suggested that perhaps solc/wrapper should be reparing this. (And then the fix would apply to everyone, not just Truffle, and we could remove our code for repairing it.) So, filing this issue asking for that.

[0]Well, OK, as of when I write this the fix isn't released yet, but it is merged...

@chriseth says that this is ok in the wrapper so we'll add a workaround.

Nice, thanks!
