mod_invites_register_web: Fix loading resources from relative paths Both module:get_option_path and module:load_resource makes the path relative to the plugin resource directory, so when running form a source checkout where this path is relative, the path was expanded relative to itself, becoming duplicated.

This module blocks configured queries that change server state.

E.g. to make vCard storage read-only:

``` lua
readonly_stores = {
	vcard = { "vcard-temp", "vCard" };
}
```
