Popover Displays Behind Modal (3.1.1)

Created by: thedavidscherer

The issue is prevalent across all browsers. It is caused by the @zindex-popover and @zindex-tootip settings in variables.less.

jsBin reproducing the error: http://jsbin.com/tesaceso/3/edit?output

This issue has seemingly popped up repeatedly over the years going back to BS 2 (that I can tell).

Changing the @zindex-tootip and @zindex-popover values to be higher than @zindex-modal resolves the issue.
