Refactored code and added modules related to tabulated Identifiers. Rearranged members of struct Identifier and added new member ID identID. Moved idTableLookup to module dil.IdTable. Renamed module TokenIDs to TokensEnum. Added member Identifier* ident to struct Token. Changed string switchtes in Parser to integer switches using enum ID.
