1. Created a t_token metatable along with support code for indexing, garbage collection, tostring, tonumber, comparison and concatenation. 2. Adjusted string comparison and lookup in lua code to work with either t_token or string. This addresses in part bug #18631, bug #18695. Before this lua was treating all t_token as either tstrings or strings.
