More code cleanup

This change comprises of multiple smaller changes:
- Convert all WriteToDat to WriteToDatFromDict, including MissFile
- Change obsolete Import to use updated ParseDict
- Remove all references to Parse
- Rename all references to "Dict" specific code to shorter names
- Remove more unused methods rendered obsolete by other changes
