Double click for run WebApp

[lp:~artem-anufrij/webby-browser/welcome-screen-and-about-dialog]

16. By Artem Anufrij on 2015-10-13

double click for open/run selected app

[Erasmo Marín (erasmo-marin)]

This is great! Just some little fixes:

1.- Add my email in about dialog <email address hidden>
2.- Add a tooltip to the "add" button

That's all, thanks!
