Addition of a new Automatic DHT Bootstrap system. This will need to be tweaked as the numbers of users increase.

Browse Source 
* hashed keys are posted to specific DHT entries, to create a series of bootstrap lists.
 * these are fetched as needed to bootstrap new clients.
 * Modified Bootstrap monitor program.

Created a minimal backup bootstrap list (temporary)
Added "-e" option to commandline to force 'external port' mode
Bugfix for multiple connection methods, could kill an active connection.
