Settings page does not save settings

When checking or unchecking boxes to enable or disable plugins on the settings page, settings are not saved. This is due to the checkbox form element being named incorrectly. The fieldset has the correct name, but because the checkbox has name="allow" in every case, the variable "allow" is being saved to the database, instead of the variable "jq_allow_PLUGINNAME".

I have provided a patch that will rename the fieldset and the checkbox names so that they are saved to the database correctly.
