Big token refactoring
...
- Extract keywords, literals and combo tokens into separate sub-enums
- Add a macro for quickly generating all tokens including the sub-enum
tokens. This also takes less chars to write

Implement vec based scopes
...
- Replaced vartable hashmap with vec
- Use linear search in reverse to find the variables by name
- This is really fast with a small number of variables but tanks fast
with more vars due to O(n) lookup times
- Implemented scopes by dropping all elements from the vartable at the
end of a scope
