Subject: [PATCH] AutoFieldWidget linked class autoloaders, etc.

* leave linked selector disabled until entries are fetched;
* added support for applying default linked class object loaders;
* added default loader for acq providers, since large sets of
providers can take an excessive amount of time w/ direct pcrud call.
