Make resource ($USERx$) macros available in the GUI

The patch is rather simple. We just let the read_main_config_file()
function in cgi/cgiutils.c grok the "resource_file" variable and
move the function read_resource_file() from base/config.c to
common/macros.c so that it's linked into the cgi's as well as the
core daemon.

Signed-off-by: Andreas Ericsson

The attached patch is also available in the gui/resource-macros branch
of git://git.op5.org/nagios.git. To merge it, use the following command:

git pull git://git.op5.org/nagios.git gui/resource-macros

A customer requested this functionality, and since it was so simple
to arrange it was a nobrainer really.

Also attached as a /usr/bin/patch compatible unified diff that applies
cleanly on top of latest cvs head.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
