[sugar] Debugging activities

[Marco Pesenti Gritti]

Hello,

I made it easier to run activities from the command line, so that you
can see the full output or run it in gdb for example.

With the sugar shell running you can do:

sugar-activity [bundlename]

Where bundlename can be just a part of the activity name or service
name.

Examples:

sugar-activity web
sugar-activity tamtam

You can do this both inside or outside the emulator.
