mention SELinux about manual HOT 4 OPEN

FWIW I just opened a (small) PR explaining the permission "pitfall" for web server content, since I was confused by this: #180

from manual.

@The-Compiler, your PR reads "For the webserver user to be able to access the files, they need to have a SELinux role of httpd_sys_rw_content_t."

Wouldn't httpd_sys_content_t be a better value to put as default in the docs, i.e. allow read-only access from DocumentRoot only by default?!

@Sgt-Nukem that's in fact what the documented restorecon -R command does when you execute it: it sets httpd_sys_content_t according to the SELinux policy:

[root@stardust ~]# semanage fcontext --list |grep /var/www
/var/www(/.*)?                                     all files          system_u:object_r:httpd_sys_content_t:s0 

I updated the text to match reality in a15e8cf.

Whoops, sorry and thanks!
