libraries 7.x-2.1

This is a minor update with two new features. It is fully backwards-compatible with version 7.x-2.0.

Be sure, however, to run update.php (as always)!

New features

• Themes can implement hook_libraries_info() in their template.php file. The usage is identical to that of modules.
• There is a new callback group: 'pre-dependencies-load'. Callbacks in this group are called right before the library's dependencies are loaded. When loading a library the flow now is the following:
  1. 'pre-dependencies-load' callbacks
  2. dependencies are loaded
  3. 'pre-load' callbacks
  4. library itself is loaded
  5. 'post-load' callbacks
