docs: autogenerate search.php

This patch makes search.php autogenerated from search.php.in, thus
removing hardcoded menus, footer etc. and the search.php is added to
.gitignore.

There is new rule added for *.php files (to make it bit less
hardcoded) that takes *.php.code.in and injects it inside the
generated *.php (xslt was not happy about php code in the source xml).
