Bug 10411: add cache control headers for static resources (Debian package)

This adds caching directives to the static resources so that the browser
doesn't ask about them all the time.

By default, Debian apache doesn't have the required module (mod_expires)
enabled, and so this patch will have no effect. In order to enable this
function, run:

a2enmod expires

and restart apache.

Test Plan:
* Using firebug or equivalent, load a page.
* Note that none of the images, css, or js files have a Cache-Control or
  Expires header set.
* Add this patch, redeploy the package with it (or overwrite the
  apache-share.conf file) enable the 'expires' module, restart apache.
* Force-reload the page
* Note that the images, css, js now have Cache-Control and Expires set
  for 12 hours into the future.

Bug 8911: make sure history.txt gets installed where history.txt can see it

This patch makes Makefile.PL put the history.txt file in the right places
depending on the chosen setup layout, adds a reference to that place in
koha-conf.xml (and debian template version), and finally tweaks about.pl to
use it.

To test, apply the patch and verify that perl Makefile.PL runs fine, and
installing in
 - dev
 - single
 - standard
layouts works as expected. Then go to the about.pl page and see if Koha's
history shows there.

Then, build your packages and test on your newly created instances.
