Support new extensions and functionalities used within ResearchKitOnFHIR to text field properties

[Supereg]

Problem

We recently added some new functionality and extensions to ResearchKitOnFHIR which is currently not supported by the survey builder.

Solution

The following new extension have been added for iOS specific questionnaire rendering:

• http://bdh.stanford.edu/fhir/StructureDefinition/ios-keyboardtype mirrors the UIKeyboardType on iOS to control the keyboard layout
• http://bdh.stanford.edu/fhir/StructureDefinition/ios-textcontenttype mirrors the UITextContentType on iOS to control autofill behavior
• http://bdh.stanford.edu/fhir/StructureDefinition/ios-autocapitalizationType mirrors the UITextAutocapitalizationType on iOS to control autocapitalization behavior.
