Post-1.10 location entry auto-completion

[Peter Harvey <peter a harvey gmail com>]

Hi all,

After the coming release we are planning to switch to SQLite for
bookmarks and history. This will take a fair bit of work, but should
result in a much faster system.

Part of the change would involve a re-write of the auto-completion code
for the location entry. The location entry is one area where the
hierarchical bookmarks code has *not* been added and so bookmarks are
just lumped together in the auto-completion. I would like to try and
improve this for the user, so I've created two simple screenshots of how
I think we could improve things for the user.

Please have a look and let me know if they would improve things for you.
Other options include:
  * Bolding that component of the bookmark that led to it being shown
  * Using alternating blocks of colour down the left side to indicate
    groups of bookmarks, rather than using horizontal lines.
  * Writing the names of each group horizontally on the first line,
    rather than vertically as shown.

Note that within each group of bookmarks we would sort alphabetically.
My screenshot shows no sorting at the moment (I couldn't be bothered).

Regards,
Peter.

PS. It's not certain how easy it would be to get these to work with GTK+
in it's current form. We'll sort out the details later. :)
