BlackBerry Development Environment Setup Wizard

This wizard tries to make the process of setting up a new development
environment for BlackBerry devices easy. It does not implement anything that
isn't already available through the BlackBerry category under the "options"
menu, and also imposes some restrictions for the sake of simplicity.

It will:

* register CSJ keys
* create developer certificate
* create SSH keys to a default location
* request a debug token
* upload a debug token to the device
