Fixes messages.txt's modification timestamp not being updated.

This bug occurs on systems where writing a zero-length string to an
empty file does not update the file's modification timestamp.

Fix nested triggering of the same event

Previously when in an event handler the same event was triggered again,
only the handlers for the second event invocation were all executed, the
handling of the "outer" event stopped after the handling of the inner
event as they both used the same iterator of the hooks array. This
caused caching bugs e.g. when both the include and the indexmenu plugin
were enabled as both of them load metadata in the cache handler which
triggers another renderer cache event.
