Solidity Compiler - solc new API
* adapt to new compiler versioning * use compiler version as language version * implement new solc API for versions >= 0.1.[2-9][0-9]* fixes #1770 * add optimize=1 to options * backward compatibility (for now) for <= 0.1.1, and old versions (0.[2-9][0-9]*.[0-9]+) * introduce compilerOptions to ContractInfo * clean up flair, include full version string to version line and ContractInfo
