Clarify solc unavailable message

See original GitHub issue

What was wrong?

The error message is not clear, when solc isn’t available.

Examples:

Proposal: catch and reraise the exception with a note saying something like:

The command line tool solc wasn’t found. Try python -m solc.install v0.4.17 or see http://solidity.readthedocs.io/en/latest/installing-solidity.html

Yeah, if solc isn’t on your $PATH you can either add it to your $PATH or set the environment variable SOLC_BINARY to the path to the solc executable.

I think the right place to catch this is in in solc/wrapper.py#L53 and to use solc.utils.filesystem.is_executable_available to check that solc_binary is present. We can then raise a FileNotFound error with a friendly error message.
