Bug 7511 [ENH] Template caching (T::T feature)

Just add to your Koha configuration file
<template_cache_dir>/path/writable/by/apache/user</template_cache_dir>
in the <config> block, and Koha will use template caching, for about
10% CPU time saving.

on linux servers, /tmp is usually OK

(also fixes an indenting with a TAB)

The results of using this are very striking. Based on an insufficient
sample size, it would seem that the time spent in T::T is reduced by a
factor of at least 5.
