Commas in sig_names field are not being parsed properly

[aknot242]

Certain requests produce signature names that have commas in them. For instance, a request of http://hostname/?category=Gifts%27+SELECT+IF(500<1000, YES","NO") shows a value of:

sig_ids: 200002437, 200002228, 200000075

However, only shows a single signature name:

sig_names: SQL-INJ
