Fix Missing Dependencies
This is not yet working - the enum constructor expects the occasional aligning value, then a list of strings which it increments the value for. I tried coercing all the values to arrayrefs with pair, but the constructor is unhappy with this. It should at least show off how this *should* work. The parameter to your FFI bound function should now be a string, e.g. 'KEY_A', and functions can also be coerced into returning string constants - see return type for `GetKeyPressed`. It's not a radical departure API-wise - rlt-01.pl should reflect the required changes

I've converted this to a draft so I don't forget that it's not ready to go in yet. I'll have a look sometime between now and TPRC and see what I can do with it. |

edit The main advantage of this is that you don't have to worry about importing constants into your namespace.
