Bug 17951: (follow-up) Make Makefile.PL handle template_cache_dir config

This patch adds Makefile.PL the capability of handling the template_cache_dir configuration entry.
To do so, it:
- Adds the --template-cache-dir option switch (consistency with koha-create)
- Sets a default value for template_cache_dir to '/tmp/koha'
- Adds a dialog requesting the path for the template cache dir to Makefile.PL
- It tweaks etc/koha-conf.xml so it is correctly changed by rewrite-config.PL

To test:
- Apply this patch
- Run:
  $ perl Makefile.PL --template-cache-dir your/favourite/dir
=> SUCCESS: The dialogs don't ask for template cache dir
=> SUCCESS: The resulting Makefile contains an entry for TEMPLATE_CACHE_DIR which value
            matches what we passed to --template-cache-dir
- Run:
  $ perl Makefile.PL
- When prompted for a template cache dir, introduce whatever you want
=> SUCCESS: The default you are offered is /tmp/koha
=> SUCCESS: At the end of the process, Makefile contains what we put in there
- Run:
  $ sudo make install
=> SUCCESS: The resulting koha-conf.xml contains a <template_cache_dir> entry containing
            whatever you picked for that purpose.
- Sign off :-D
