Add support for #foo.bar form back in. Add support for inlining words. Very WIP work on expanding words to their Python code and expanding that code in inlined words.

Fairly complete rewrite of VM. Now supports composite words with { w1 w2...}. Rewrote :, if, ifelse and while to use composite words. Namespaces now have Clojure like vars for indirection and also support inline words. Words defined in Python now use Python function decorators to add Sallyforth related metadata.

Added builtin alias word, which means we can define most of the built-in words with non-Python comparible names (think . and +) in sallyforth instead of Python. Also added backslash comments and stack reset work.

Switched the word function xface so that words now return the new ip instead of a delta. This simplifies the interpreter allows recur to simply return 0. Also changed the tokenizer so that 'foo produces a string w/o the need for a closing quote, good for symbols.
