Sometimes we patch or edit a hook to meet our specific needs.
Somtimes this leaves behind a file like FILENAME.orig. The hook
detection login still runs these other files, making for confusing
debugging issues. Use a stricter match on what makes a valid hook name
to avoid these issues.

* Allows custom logging handler on the console

This is useful for reducing noise during tests

Currently the remember me functionality does not work correctly and using it results in severable undefined index errors as the expire cookie parameter is passed along the SessionHandlerPHP which does not accept this one. Using lifetime instead of expire, effectively doing the same thing, this can be fixed in a pretty simple way. Next to that the params given to the session handler are merged with the current ones before given to the session handler instead of after.

Improve error handling

This reverts commit f1e05f8f.

The previous situation was confusing with various contradicting
(staments of) defaults, mixed with old style and new style
configuration.

Simplify by deciding that having backtraces is so
useful that it is the defaut, both old and new style configurations.
(It was already default on in the config template,
which seems 'canonical'.)
