common components for input forms instead of custom html

[shapiromatron]

Instead of using raw html for select and input components, use some predefined components to standardize the user-interface

• use the existing components/common/SelectInput; modify as needed to work
• use the existing components/common/FloatInput; modify as needed to work
• create and use components/common/IntegerInput
• create and use components/common/TextInput
• create and use components/common/CheckboxInput if this make sense (but only if it makes sense; I know the model selection items ones are already heavily componentized so they may be fine as is)
• create and use components/common/LabelInput if this make sense

Migrate from custom html to these components. It's ok to not migrate over very customized inputs if needed, but we should default to using the components when possible.
