move things around :)

Moved pager, pagination, popovers, tooltip, progress bars & type
properties to variables.less
Merge branch '3.0.0-wip' of https://github.com/saas786/bootstrap into saas786-3.0.0-wip
Vars update

* Drop progress bar text-shadow
* Reorganize popover and tooltip vars and fix complier error due to
missing `;`
* Run `grunt`
Fix broken indentation

Not sure when or how this happened, but I just noticed it—4 spaces were
used instead of 2.
More customizer changes, and revert to placeholder layout
