This patch puts the transformed pretty print DOM into a Shadow DOM.
The stylesheet is loaded with an @import in a <style> block, so the
monospace stylesheet had to be left out.
The XBL binding is kept, pending removal when Shadow DOM ships.
It's still needed to handle the case when Shadow DOM is pref'd off too.

Also remove duplicate import from the XMLMonoPrint sheet (unnamed default sheets
stay applied when switching to alternates, only named are unapplied).
Additionally fix some regressions from bug 379683:
* top-level collapsed and uncollapsible elements weren't monospaced in monospace
style.
* top-level uncollapsible elements weren't indented.
* there was an extra space between PIs and their expander control.
Based on prototype by bgrins.
