XXX in templates should be updated so they're correctly captured by the xxxreporty.py tool

[Diogo Matsubara]

We have a tool that generates a nice html report with all the XXX's found in the LP code. <https://devpad.canonical.com/~curtis/xxxreport.html>

This bug is about updating those XXX so the tool will correctly display them

<matsubara> sinzui: quick question about r6941: does xxxreport.py now include XXX in templates?
<sinzui> matsubara: it always has
<sinzui> matsubara: It may miss some of the comment text since HTML only has multiline comments. Using // or # in front of each line will ensure all the text is captured,
<matsubara> sinzui: cool, I wasn't aware of that. I'll mark bug 256212 as invalid then
<sinzui> matsubara: in https://devpad.canonical.com/~curtis/xxxreport.html you can see that from 708 on, XXX in templates are captured, but that the comment text is often shown in the context portion of the report.
<matsubara> sinzui: right. I missed those when I filed the report. I'll invalidate it. thanks!
<sinzui> matsubara: I think that bug is legitimate in part because XXX comments must always be in out XXX format, which they often are not in templates.
<sinzui> matsubara: so the fix is the review and correct XXX comments in the templates.
<matsubara> sinzui: good idea. I'll mutate that bug to say that.

The following templates have XXX pointing to fix released bugs so they are good targets to the technical debt cleanup.
templates/bazaar-index.pt
templates/binarypackagepublishinghistory-listing-detailed.pt
templates/binarypackagerelease-index.pt
templates/translation-import-queue-macros.pt

As part of this fix I need to update (and move to the right wiki while at it) https://launchpad.canonical.com/PolicyandProcess/XXXPolicy to reflect the current style of adding XXXs on templates.
