raise an error attempting to compile mirah using jruby before 1.7

we changed the bootstrapping bytecode munging to use asm4, which changed a class into an interface. 1.6.8 and lower have asm3 bundled so they can't compile mirah from source. It's still usable from them, they just can't compile it.
make tests 1.6.8 compatible
update history for 0.1.0
