Update 10_1_1.sh

1. sed -i "s|mydomain   = control.yourdomain.com|mydomain   = $fqdn|
Extra space so not working!

2. set keep alive on. Best for performance and default is on on Ubuntu

3. Hide php from server banner. For security reason and considered always better.
Merge pull request #21 from Me-Bl/patch-1

Update 10_1_1.sh, setting Apache KeepAlive to 'on' by default and removing PHP from the server headers as 'best practice' approach for server hardening.
