Another grid update

* Update docs to include table of grid levels and behaviors
* Change from .col-md to .col-sm to match existing size variables we use elsewhere
* Keep .col-lg as-is though for simplicity as we won't likely add a fourth level of the grid
* Combine responsive .container breakpoints with grid breakpoints in grid.less
* Other misc docs updates

<h3 id="grid-examples">Grid examples</h3>
<p>Bootstrap's grid system includes three levels of column sizing&mdash;phone, tablet, and desktop and up. Use each level in conjunction with the others for more control, or stick to the desktop classes for single-column, stacked mobile views.</p>
<h3 id="grid-example">Grid example</h3>
<p>On mobile devices, the grid starts out stacked. Above 768px, it becomes horizontal as media queries kick in to apply <code>float</code>s and <code>width</code>s. To create a basic grid layout, wrap a series of <code>.col-lg-*</code> elements within a <code>.row</code>. As this is a 12-column grid, each <code>.col-lg-*</code> spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent), even at mobile resolutions.</p>
