Create a templates_kcls to hold KCLS branding of TT OPAC

The debranding of the TT OPAC begins with the top navigation.
  * Replace the KCLS logo with the Evergreen logo (even though
    white background on black doesn't look great, it's something)
  * Replace the KCLS specific top links with example links.
  * Split the logo and the links sections out into separate
    templates so that we can maximize commonality of the
    topnav.tt2 template.

For now, all files containing the string 'kcls' have been
copied into the templates_kcls directory. As we move through
the templates, we may refactor them in similar to how we just
refactored topnav.tt2.
