Fix for topbar dropdown arrow position when height of topbar is increased.

The topbar dropdown arrow has a `top` position of 22px. This is
hardcoded assuming the default topbar height of 45px hasn't changed.
This fix, fixes the position of the topbar dropdown arrow so that its
top position is `$topbar-height / 2`. It also fixes maintains
consistent padding as the topbar height is changed.

Upgrading modular vars for zero output

This will change the current behavior so that setting $include-html-classes: false; and $include-print-styles: false; will produce an empty css file.

This way users can add in only the pieces they want to include by setting: $include-html-classes: false; and $include-html-XYZ-classes: true;
Update _clearing.scss

When creating a clearing gallery using block-grid for presentation, some styles interfere with the presentation of clearing.
Example:

<ul class="large-block-grid-4 clearing-thumbs" data-clearing>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li> <- This thumbnail will appear on second line
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
<li><a href="#" class="th"><img src="myimage.jpg"></a></li>
</ul>

The style for the block-grid break the presentation of the clearing thumbnails with this selector .large-block-grid-4 > li:nth-of-type(4n+1) because the fith thumbnail will be cleared and floated to the left.
Missing : in $topbar-media-query

Fixes an iPad landscape error, which didn't show topbar correct.
Nested side_nav items corrected styles

When nesting side_nav items (ul) only the direct first-child should get
a different style.
Changed font-smoothing to subpixel rendering

The antialiased mode is generally less good at rendering fine or sharp edged fonts than with subpixel rendering. (which is the default in webkit I think)
