Greatly speed up 'attach to running instance' dialog in the 99% case

Browse Source 
* 99% of the time, you'll only have localhost and the application will
  be running on the first ident checked which will return a valid socket
  almost immediately.
* Instead of continuing to search through each valid port before
  returning valid data, we change the enumerate function to just find
  the next valid port and return - so we can update the UI as soon as
  we have the first result.
