consider using the "standard json" interface of solc

[axic]

The compiler expects a JSON formatted input (with all sources, required outputs and settings) and returns a JSON with all the required outputs.

working on a wrapper around solc/solcjs over here https://github.com/snd/rust_solc that will use the standard json interface. soon we'll be able to replace the solc part of sol-rs by it.

unfortunately "standard json" seems broken for solcjs: argotorg/solc-js#126

i'll might still implement it but this makes it somewhat less useful as people will need solc (C++) to use it and can't choose
