Restructuring the debugging wiki pages

[Henrik Nilsen Omma]

In an effort to improve the debugging workflow and to reduce the barrier 
to entry for helping out we are re-evaluating the structure of the 
debugging wiki pages.

One proposal is to change the URL naming scheme so that it corresponds 
directly to the package names. This would make it easier to make use of 
the information via tools like launchpad and bughelper, and it will be 
more clear where we need to add further information (where the pages are 
missing).

The URLs would become:
https://wiki.ubuntu.com/debugging/<package-name>

However this means we'd get a very large number of pages, and many would 
not be very useful. As an example, we currently have a 
DebuggingTelepathy page, and several packages with the word 'telepathy' 
in the title, but no simple 'telepathy' package.  We also have several 
pages that are more general, including DebuggingGNOME and 
DebuggingUSBStorage. Such grouping seems useful in many cases.

Instead I propose we stick largely to the current page naming scheme of 
Debugging<PageName>, where <PageName> may or may not be a package name. 
The pages should be based on a common template, as with the spec pages. 
Here is a first draft template page: 
https://wiki.ubuntu.com/DebuggingTemplate

In addition we should have a few generic pages:

 - Debugging - The landing page with a brief overview of the available 
information.
 - DebuggingUbuntu - Generic advice on debugging in Ubuntu.
 - DebuggingPageIndex - link packages to debugging pages (see 
https://wiki.ubuntu.com/DebuggingPageIndex)
