Calx on cloj1.4

[LudoTheHUN]

Hello Zach.

Here is a version of calx running on clojure1.4 (I think it's good on 1.3 too). The major difference is that little endian version of buffer frames have to be used.

I've taken the liberty of adding in lg_ versions of some of the functions which allow for passing of the openCL environment, these are tested in the test file lg_env_passing.clj.

If anything is not to your standard, please feedback on how I can improve it.

Regards.

Ludwik.
