While it's not strictly needed for "mod" plugins, the general rule is to use plugintype_pluginname for admin settings. Right now we are using just pluginname. Note that all the subplugins are already using correct plugintype prefixes (surveyproformat, surveyprofield, surveyprotemplate, surveyproreport).

So, this is about:

1) change the settings to be mod_surveypro.
2) change all uses of them in the code if needed.
2) bump version.
3) provide an upgrade script to move all the old (4) names to the new ones.

That's all. Ciao
