Implement PharoLauncher workflow

Extract from the mailing list:

Thanks Juraj. This is great. I saw your testing in the discord chat and was curious.

This reminds me, one thing I've wanted to do for a long time is type an Issue number into PharoLauncher and have it download latest Image, get the issue title from Fogbugz to rename the Image, start the image with a script to open Inbox ready on the Issue.

If I ever do get to it, mixing in your sprint app might be cool.
