Touch-based session launcher

As much as I appreciate the command line, sometimes I just want to launch a session quickly without having to (correctly!) type the hostname. Some options (either of which I'd be fine with) would be:

- opening new windows with a speed-dial type interface such as in a Web browser (e.g. in Safari when tapping the address bar), for which one option would be the Blink command line

- adding recent hosts / configured hosts to the session overview if implemented (#9), perhaps similar to how iCloud tabs are shown in Safari

In my case, just having all my sessions open all the time (#59) would solve a lot of the problem, so if that gets implemented first, this would be a lower-priority item.

Thanks!

The issue names no implementation files or tests. Start by reading related issues #9 and #59 and reviewing the existing session overview and Blink command-line entry points. The issue leaves two possible designs open, so completion requires selecting a launcher behavior and defining how recent or configured hosts can be opened without typing the hostname.
