Update to comply with new 2-arg arity of IJavaScriptEnv in 0.0-2665.

[mfikes]

Since this is a breaking change, update Weasel version to 0.5.0. Additionally, since this is incompatible with ClojureScript versions prior to 0.0-2665, eliminate the temporary compatibility hack for previous API breakage introduced with 0.0-2371.

This addresses #37. If this is ultimately released, the CHANGES.md can be updated to reflect the breaking change, along with README.md.

@mfikes thanks for doing this. tried out this PR, but having some trouble with piggieback, did you have to modify it? Minimal weasel project here with steps to reproduce in the readme: https://github.com/shaunlebron/new-weasel-example

@shaunlebron Yes, there are two -setup calls in piggyback that will need to be updated. Locally, I simply passed in nil to get by:

Thanks, confirmed it is working. Created a piggieback PR #37 with the necessary changes; we'll have to wait on that before merging here.

Updated working example for verification: https://github.com/shaunlebron/new-weasel-example
