Implement password reset tokens without cache

[mbrodala]

Currently the TYPO3 caching framework is used to store password reset tokens. If the caches are flushed, all tokens are lost which results in broken links for users which have started a password reset before the flush.

The password reset tokens should be stored in a custom table or at least in the TYPO3 registry. We still need some kind of lifetime and garbage collection though.

Thats why I implemented a VariableFrontendUnFlushable specially for the hairu_token cache.

Sorry to make you go to such lengths to work around a stupid decision of mine. :-(

No big prob as I found this smart fix! Don't let it trouble you to much! There are more worst things you have to fight with from time to time :-)
