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'.

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