Feature request: redirect based od 3rd domain level

[lubomier]

Hello,
i would like to have an option for custom urls (not random hashes) to be redirectable by domain name.

1. Current behaviour:
   yourls.org/mycustomurl -> example.com

2. Desired behaviour
   yourls.org/mycustomurl -> example.com
   &&
   mycustomurl.yourls.org/-> example.com

This requires server specific configuration and this is hosting / server dependent.

A possible solution would be to add rewrite rules to map subdomain to subdirectories. See for example https://stackoverflow.com/questions/10642426/htaccess-rewrite-subdomain-to-directory.
