Add Android Monkey support

[StErMi]

Can you add to the test batteries Android Monkey support?

This will be really a nice feature :)

Here's the link for the monkey: http://developer.android.com/tools/help/monkey.html

What would you envision the output to look like? There aren't any individual test results to report or screenshots to display which is the core feature of Spoon.

Ou ok, I thought that Spoon would be a really good general-testing project.

Could you provide every x secs take a screenshot for monkey ?
