userid lookup caches: use 1 on-disk cache file, update cache rather than rebuild Before this, we maintained one cache file per attribute (e.g. name2id, openid2id, ...) - the related code did multiple passes over all user profiles to rebuild these cache files. Now doing a one-pass rebuild, writing all attribute -> userid mappings into one on-disk cache file called "lookup". Additionally to "name" and "openids", support fast lookup for "email" and "jid" also. On profile save, we use to just kill the cache and let it rebuild. Now the cache is read, updated and written back (which is much less expensive for wikis with more than a few users). Did some refactoring also, reducing duplication, breaking down the code into smaller functions / methods.

Verify that the MoinMoin source files conform (mostly) to PEP8 coding style.

Additionally, we check that the files have no crlf (Windows style) line endings.
