Add autocomplete provider for "about:" URLs.
This is a reworked version of r74451 that makes the following changes:
* Removed function to convert an about: string to a URL. We don't need this in the autocomplete side because the "about:" URLs will be correctly handled when the user hits enter; and removing it means we don't need to ensure that the data provider is initialized, because that will also be done automatically.
* Clean up the about:about HTML construction to be shorter and produce slightly more readable source code
* Remove about:vaporware (cleared with thakis, who added it)
(Obviously, the last two changes are "while I'm here, ..." cleanups.)
BUG=6870
TEST=Typing "about:s" into the omnibox should result in a couple of "about:s..." URL entries in the dropdown even if you've never visited them.
