Template cache introduced to shortcut expensive compileCode() calls:
- New template caching added which requires you to delete
  inc/cache/templates/foo.tpl.cache if you have edited foo.tpl
- TODOs.txt updated (again some more internal TODOs are closed, some are added)
- getDateTime() call removed from loadTemplate() to speed it up
- Other minor fixes
