(corrected) added output for snmp php module check

curious if this is the section you were wanting the output to be in regarding the snmp check?
if not, I assume at the bottom where information about mb2md and disk space recommendations are at.

if this isn't correct, please let me know and I can create a variable to be checked and output at the bottom.
also, I need to get a key set up for our plesk server to test
