Refactor variable input form control generation

This change moves variable input form control generation from Java code in
InputGeneratorVisitor to enterVariables.jsp itself via the new custom tag
variableSpecific. Not only does this allow more natural HTML output, but permits
using other custom tags for the input controls.
ASRC-42: preserve variable inputs

even in the case of validation errors
