Fixed sample for checkItemsNotAvailable in VoyagerRestful.ini.
Fixed comment for defaultRequestGroup setting in VoyagerRestful.ini.
Hooked up help text display to hold form.
Added missing help texts to ILL and storage retrieval request forms in bootstrap theme.
VoyagerRestful: Added a set of options for fine-tuning hold behavior.
Changed the default translations of "request group" to be more generic.
Removed extraneous code left over from a previous development version. requestGroupsEnabled is now controlled by extraHoldFields, so this code is unnecessary.
Improved Demo driver so that hold level is conveyed properly.
