Support auto completion on discovered bookmarks and filling out params

Summary:
This diff adds support for finding appPatterns (not sure how the feature is called) in the device, and auto completing on it.

Also improved the styling of bookmark sections.

This diff also adds support of showing a dialog in which params an be filled out if needed.

The behavior around optional arguments seems buggy, as in, no dialog will show up, but since I didn't want to change the logic around this unilaterally, left it as-is for now.

Updated the dialog to Ant so that the renderReactRoot utility could be used safely
