Added Bootstrap-Select

Hi Robb,

Sorry about the repository confusion. I've integrated the Bootstrap-Select plugin from http://silviomoreto.github.io/bootstrap-select/ into Patternfly and adjusted it to match RCUE standards. The plugin handles both single- and multiple-selection. The only problem we may have is the lack of submenus/flyout support, because form elements can't be nested like list elements.

Thanks,
Susanne

Single-select and multi-select dropdown plugin for Bootstrap. Does not
handle submenus/flyouts.
