swaps between 1.14.5 and 2.1.0.19 compilers

Run `./swapCompilers.sh` and confirm which version of Naoqi you are currently compiling for in order to swap to the other version. You must restart your terminal after swapping, otherwise the changes made to nbites.bash will not take effect.

This is for use during Brazil 2014 only. When competition is over we NEED to sort out naoqi issues and get all robots up to 2.1
