fix(fabSpeedDial): fix many visual issues

* maintain state when focusing/bluring/tabbing through actions

   speed dial would previously show a very short and erroneous animation
   when tabbing, or rapidly blurring/focusing, through child items

 * add demo showing tooltip usage

 * fix $digest in-progress error when opening a dialog

   cebor reported a $digest in progress bug when trying to open a dialog
   from within the speed dial; haven't figured out how to create a test
   that demonstrates it, but I added a demo which shows failure

 * animations fail on Safari

   update webkitTransform styles and set height to initial instead of 100%

 * make changes suggested by gkalpak

 * more fixes suggested by gkalpak

closes #3213. closes #3338. closes #3277. closes #3236. closes #3375. Closes #3468.
