Replace all @@-variables in pagespeed.conf.template.
Replace all @@-variables in pagespeed.conf.template.

    	Add 2 levels of testing for this:
    	1) Test in installer.include that there are no @@'s left in pagespeed.conf file.
    	2) Actually restart httpd after purge/install of new binary on VMs, this will check that the default configuration does not cause httpd to crash.

    	Also added a fix to PSOL binary building.

    	Fixes issue 742.
