Release 2 6 1

[jeffikus]

Fix release:

• smoothHeight now uses innerHeight() instead of height() to account for padding in calculation.
• Defining var altText to prevent error.
• bower.json add fonts folder on main field.
• Changed true to false in order to make sure whether or not to allow a slider comprised of a single slide.
