moving icons in subdirectory
Gruntfile changes:
- set /yaml as compass image directory reference
- copy image files (png, gif, jpg) into yaml css directory
- replace image path in microformats css files
- do copy task before compass task, so the copied images could be found and used by compass
use inline-images() compass function for inlining base64 images in microformats.scss and create a fallback version for sprites
microformats files after build process
