Only avoid collision if it's the same file

@chriseth had suggested that it would be better if contracts were
referenced in a file:contract notation, and that we output .bin files
that prepend original path names if necessary to avoid a collision.

This commit is mostly a draft; it still needs to be run through the test
suite.
