Various fixes for khotkeys. This resolves issue #326.

1. ensure there is a single khotkeys instance running per session
   instead of per screen (remote multihead related code)
2. allow khotkeys to be run as a kded module
3. make sure that khotkeys run either as a standalone application or as
   a kded module, but not both at the same time
4. do not register khotkeys as a main DCOP entry (like an app) anymore.
   When run as kded module, this was causing kded to be registered as
   khotkeys a second time.
