TEIIDTOOLS-124: Changing spinners

* Patternfly spinner is, by default, centred but its position is limited
  by adding them to columns that are not the width of the page. Consequently,
  they look odd being misplaced at varying points across the screen.

* Overrides spinner's margin-left property to dictate the spinners to be
  on the left.
