Many big fixes compared with 1.96.3. In particular:
- explicitly closing all open files (should make it work in Pypy), thanks Caleb - even better security in uuid (thanks Jonathan and David) - template decoupled from web2py, thanks Ryan - fixed a typo on Oracle nested selects - better support for "id" fields not called "id" - auto import should work on windows (now on windows ignore will ignore case by default)
