* Nuke the commented out navbar forms code that's not currently needed
* Add a few more examples to the .navbar-form docs section
* Remove (for now at least) top padding on checkbox and radios

* Remove .input-mini because who really needs inputs that small
* Remove unnecessary border-radius resets from large and small input groups

* Restore forms.less file
* Overhaul .radio.inline .checkbox.inline to be .radio-inline or .checkbox-inline
* Update docs to reflect changes

Remove .controls-row; instead, folks should use .row and .span* for all their grid input sizing needs when multiple inputs per line are required

this is a resubmission of #5875, but now against branch 3.0.0-wip
does not exclude elements under a fieldset's legend
issue #6058 is a duplicate of #5605

* Deprecate .input-append and .input-prepend
* Use new, single base class for component, .input-group
* Deprecate .addon for .input-group-addon
* For compatibility with all buttons, require .input-group-btn to wrap buttons and button dropdowns
* Still need to reimplement with segmented button dropdowns, but that's dependent on a refactor of those first
