Improvements to debug/perf info on smaller screens
Remove unnecessary block_html stylesheet exclusion

The block_html stylesheet has been removed, so no longer needs to be
excluded.
Navbar: add extra padding to breadcrumb on small devices

In order to make it easier to tap the breadcrumbs on a phone, extra top
and bottom padding is added at widths below 767px.
Make question bank faux-block title more consistent with real blocks

The fancy border from real block headers has been omitted.
Remove unnecessary moodle-dialogue-base styles

The z-index was causing the filepicker to appear behind the TinyMCE image
popup.
Awesomebar: Touch Mode for small devices

This is very definitely geared towards touch devices, so may be a little
awkward to use on non-touch devices with small screens/browser windows.
As this is a first cut, there may also be other rough edges.
Version bump to 2.0 BETA 4
