Bug 11349: Change .tmpl -> .tt in scripts using templates

Since we switched to Template Toolkit we don't need to stick with the
sufix we used for HTML::Template::Pro.

This patch changes the occurences of '.tmpl' in favour of '.tt'.

To test:
- Apply the patch
- Install koha, and verify that every page can be accesed

Regards
To+

P.S. a followup will remove the glue code.

Bug 11349: Remove unnecesary name translation

Since all scripts use the '.tt' sufix for template names
there's no need for and regexp that changes from '.tmpl'
to '.tt'.

Bug 11349: Make the QA script happy

This patch just adjusts several POD stuff, and in a few cases
reorganizes a hash definition in order to use spaces instead of tabs
for the QA script to be happy.

Nothing important, really. This patch series just changes '.tmpl' for
'.tt'.

Regards
To+

PS beware that running the koha-qa.pl script can take lots of time on this one
:-D
