Experimental testing: using Name Resolver in Find Dialog

Improvements needed (which is why this is not the end of it):

1. Enable the resolver machinery using a flag in the FindDialog
   constructor.

2. Find Dialog should show a phantom entry (eg: "Search the internet")
   to present users that option.

3. We must commit the newly created DeepSkyObject gracefully into some
   SkyComponent so that it appears in objectNearest() searches and
   other such places.

4. Allow commiting the newly created object into the SQLite Database.
