added the ability to enable/disable pushover, couchpotato, and sickbeard support from the config file.
fixed the dump site folder not existing (issue #7)  previous fix checked to see if the source folder exsisted and then created it.  should have checked on the destination folder.
Fixed loading from config to fail a bit more gracefully.  Also go the "ENABLED" fields in the config files to work.  Stupid getboolean.
