Compatibility with react-bootstrap 0.29.x (deprecation of <Input>)

[chrismcband]

React bootstrap has some changes in 0.29 which means Input is being deprecated.
The console outputs these warnings:
Warning: is deprecated. Use, , or , with and/or as needed instead.

Warning: "hasFeedback" property of "FormGroup" has been deprecated. Use a <FormControl.Feedback> element.

The library still works, just with plenty of warnings in the console, but this will need to be addressed for when <Input> is eventually removed.

I'm working on a new version that will have a lot of improvements and support all updated dependencies including react-bootstrap. No ETA though.

Cool, that's good to hear.

Well, react-bootstrap 0.30.0 now breaks compatibility with react-bootstrap-validation. Can confirm #67 works.
