Drop .table-reflow

Tried redoing this in flexbox, but it falls apart really quickly. Any changes in height of the cells throws it all off since the rows become columns (and thus, content across columns cannot be equally sized). Rather than implement something with such glaring flaws, I'm nuking it outright.

-### Reflow
-Turn traditional tables on their side by using `table-reflow`. When using reflow, the table header becomes the first column of the table, the first row within the table body becomes the second column, the second row becomes the third column, etc.

-#### Content order and complex tables
-
-Beware that the `table-reflow` style changes the visual order of content. Make sure that you only apply this style to well-formed and simple data tables (and in particular, don't use this for layout tables) with appropriate `<th>` table header cells for each row and column.
-
-In addition, this class will not work correctly for tables with cells that span multiple rows or columns (using `rowspan` or `colspan` attributes).

 - Responsive tables no longer require a wrapping element. Instead, just put the `.table-responsive` right on the `<table>`.
 - Renamed `.table-condensed` to `.table-sm` for consistency.
 - Added a new `.table-inverse` option.
-- Added a new `.table-reflow` option.
 - Added table header modifiers: `.thead-default` and `.thead-inverse`.
 - Renamed contextual classes to have a `.table-`-prefix. Hence `.active`, `.success`, `.warning`, `.danger` and `.table-info` to `.table-active`, `.table-success`, `.table-warning`, `.table-danger` and `.table-info`.
