Bug 12549: Hard coded font Paths ( DejaVu ) cause problems for non-Debian systems

Allows for selection of DejaVu font path when installing from the command line. This
is useful for non-debian distributions that don't store the fonts in the same place.

Adds a new configuration variable to Makefile.PL: FONT_DIR

Defaults to the Debian install location for the fonts.

Test plan:
1. Run a CLI install, accepting the defaults.
2. Compare the generated koha-conf.xml to a
previous install - the font path for DejaVu fonts should be the same.
3. Run another CLI install, this time choosing a custom path for the fonts
4. Check that the path selected is reflected in the koha-conf.xml file.

NOTE: 'perl Makefile.pl' and 'make' generates blib/KOHA_CONF_DIR/koha-conf.xml
      ran with a weird string for the font dir
      copied that koha-conf.xml to my home dir
      reran with all defaults
      compared the two, and only the font paths differed.
      Also, I cleaned up the tabs that snuck in. :)
