A(nother) MOP for Perl 5

This is a second attempt at building a MOP for Perl 5, this time with significantly scaled back ambition.

The goal is to still have the same syntax, but to make the MOP itself much less complicated, therefore hopefully making the implementation ultimately more maintainable. Additionally this is being built from the start to be compatible with old-style Perl 5 objects and to try to lean on existing Perl conventions instead of inventing a bunch of new things.
