Changeset 17669

Importing Duster theme, first pass at a candidate for twentyeleven theme.

Nice to have, but optional, improvements it'd be nice to have:

• Ability to have random rotating headers. (Core improvement to custom header functionality.)
• Color and layout options.
• More post formats. (Currently supporst Asides, Links, and Galleries.)
• CMS-style slider home page option.

Welcome, TwentyEleven née Duster. :) Track at #17198.
