Downgrade nginx module to 0.0.10

Current nginx module complains:

> Could not retrieve catalog from remote server: Error 400 on SERVER:
> $worker_connections must be an integer.

This appears to be non-trivial to fix, with the maintainer stating [1]:

> We're actually right in the middle of some major changes to this

So, downgrading seems like a reasonable option for now.

ocf_www: add php5 fcgi wrapper source

We use a wrapper for virtual hosts to provide PHP via FastCGI (instead
of suPHP). This is significantly faster than suPHP, and not much more
complicated than not doing it.

This also allows PHP-using vhosts to benefit from APC. The scripts which
build vhost definitions are in ~staff/vhost and currently not in
revision control (they should probably be moved to utils).
ocf_www: switch from mod_fcgid to mod_fastcgi

Using mod_fastcgi allows us to use tha "autoRestart" option to
automatically restart a FastCGI process when the mtime of the script is
updated (i.e. when touching the script).

Note that this requires a change to the vhost config files, which
currently use FcgidWrapper to define a specific wrapper for php scripts.
ocf_www: enable actions module

We use the actions module to use a specific FastCGI wrapper for .php
files for virtual hosts. Virtual hosts are special because they each get
their own FastCGI PHP wrapper; we want to use this wrapper so that
vhosts get improved PHP performance (can benefit from APC, etc.).

This change is necessary because of the switch to mod_fastcgi, which,
unlike mod_fcgid, doesn't support defining a wrapper script for only
files of a certain suffix. So, instead, we add to each vhost:

    AddHandler php5-fcgi .php
    Action php5-fcgi /php5-fcgi
    Alias /php5-fcgi /opt/suexec/$login/php5-fcgi-wrapper

...which achieves the same thing.
