Objects are now separate from {} dictionaries
the . operator now only indexes fields on objects, the [] operator can only be used on objects if the __index or __newindex functions are defined
Additionally 4 new instructions have been added to the VM: OP_NEWDICT, OP_INDEX, OP_INCINDEX, and OP_NEWINDEX.
The syntax to create a dictionary is as follows { <key> : <value>, <otherkey> : <othervalue> } eg. { "hello" : "world", "foo" : 1337 }
The Lexer & Parser was extended to add the TOKEN_COLON ':' token.
