Clarification and missing file

After some research a finally solved the mystery. Due to changes in the way that C32 v2.xx handles the linker scripts the boot loader won't work if compiled with those versions. I don't really make any changes, except the removal of the missing file in the project and added the prebuilt hex files for every platform. Also added the warning about the compiler in the README file.
