Initial language designs & lexer from crafting interpreters

The very initial language designs I came up with for Sloth. Likely
contains inconsistencies and definitely contains things that will be
changed in the future. This is basically just a dump of every idea I've
had for the language thus far.

As for the lexer right now it is heavily based on the one from the
Crafting Interpretrs book and doesn't yet parse Sloth grammar.
