[Feature Request] Curate tab: click Content File to insert matching Launch Command

[nosamu]

Describe the issue
The Curate tab includes a listing of Content Files. Right now, one of the easiest ways to fill in the Launch Command is to type http://, then copy and paste the file path of the applicable Content File. But that takes a few steps; the launcher could make things a little easier.

Describe the solution you'd like
The launcher could automatically fill in the Launch Command field when the user clicks one of the listed Content Files. For example, if the user clicked www.example.com/games/some.swf, the launcher could fill in http://www.example.com/games/some.swf for the launch command.

Describe alternatives you've considered
Another idea is to add a "Copy URL" button next to each content file, which the user could then paste into the Launch Command field.
