New acceptFrom feature

Thanks to @mfriesen for adding the new acceptFrom option.

This option is a replacement for the soon to be deprecated connectWith option.
The benefit of this new implementation is, that sortables can have a one-way connection so that items can be move from sortable A to sortable B but not vice-versa.
