Merge branch 'master' into gh-pages
Made spacing and Alignment optional

- Included variables to control spacing and alignment class output.

- Changed the way spacing and alignment classes output, so there are
always silent classes available, but true classes are optional. Best of
both worlds.

- Fixed a bug where headings were outputting negative margins on p tags
at every media query. This was unnecessary.
Cleaned up comments

-Made comments single-line rather than block so they never get output.
This should make debugging cleaner and source maps easier to untangle.
Typography fixes

- Made typography baseline more accurate with edge cases.

- Converted more stray block comments to line comments.

- Changed base theme to proposed Nu-Connect theme.

- Fixed some tab issues.

- Removed button inherit style (better suited for classes).
Added print styles

-Created print.scss

-Separated print styles into their own stylesheet for better
performance (styles linked in the head that do not match the user's
media do not cause blocking).

- Updated meta.kit to link to print.css.
New font mixins

-Incorporated compass' font family mixin.

-Included a new mixin for fonts that automates the font-face generation
process.

-Changed font names to conform to new code standards.
New blend modes

-Added photoshop-esque blending modes under colors/_blendmodes.scss
Spacing and tab cleanup

- Made spacing more extend-heavy. This lightens the output css
extensively.

-  Made tabs more modular, making extra styles completely optional.

- Moved $tab-borders variable more flexible. Now either false or a
color rather than a separate variable for both.

- Added align_none to alignment options.

- Moved hide and show options out to utilities/_helpers.scss
Added string helper functions

-Added a string-contains function.

-Added a string joining function.

-Removed debug output from font-sizing.
