The user was nameencoded twice.

This plugin converts existing filenames that were stored using the
option "safe" in fnencode from using the dot (.) as post_indicator to
using a bracket (]) as post_insdicator. It will also add a
post_indicator at the end of the file name should it be missing (Bug
FS#2122).

This plugin needs testing by people using the safe encode option!

Attention: $lang['register'] has been renamed to $lang['btn_register'],
anyone using that in any plugin or template should adjust it.

This patch makes the plugin manager not descend into symbolically linked
directories as this behaviour is not expected from a recursive delete.
