Patch for plugin whitelist_soft to allow regulat expressions in recipients

Attached you find a patch for the whitelist_soft plugin to allow regular 
expressions in the whitelistrcpt configuration file. Regular expressions 
have to be enclosed between slashes to differentiate between the old 
string matching and the new regular expression matching behaviour.

It is useful if you like me use special addresses to e.g. register at 
web sites and don't want to wait for an hour to get the opt in mail due 
to the greylisting plugin.
