Have stub file for solidity version

[yaronvel]

Create version.sol that would include only
pragma solidity ^0.X.X;

All our files (e.g., not zeplin's) should import it.

why?

[yaronvel]

So when we upgrade to a new compiler we wouldn't have to change many files.
Just a thought.

[yaronvel]

Never mind. Tried to use it.
The compiler still issue a warning about missing pragma, even when the first line is to import version.sol.

[jellegerbrandy]

I assume the importer just skips the pragma - it is a statement about the file itself, not an instruction in solidity.
