Flask-assets2

This release is compatible with webassets 0.8.

- Flask-Script's ``build`` command now has ``--parse-templates`` option.
- ``Environment`` class now has ``from_yaml`` and ``from_module``
shortcuts (Sean Lynch).
- Jinja2 filter uses the Flask template environment.
- Fixed PySscss filter.

This release is compatible with webassets 0.7.

- Now officially requires at least Flask 0.8, so it can use the new
extension import system, but using the compatibility module, older
Flask versions should work fine as well:

- Support Python 2.5.
- Allow customizing the backend of ``ManageAssets`` command.
- Due to webassets 0.7, the cssrewrite filter now works with Blueprints.

- Fixed Blueprint/Module resolving in output path.

- Building in 0.6 was very much broken (thanks Oliver Tonnhofer).
- A custom "static_folder" for a Flask app or Blueprint/Module is now
supported.

- Support webassets 0.6.
- Fixed use of wrong Flask app in some cases.
- Fixed init_app() usage (Oliver Tonnhofer)
- Python 2.5 compatibility (Ron DuPlain)

- New version numbering scheme. The major and minor
version numbers will now follow along with the version
of webassets the Flask-Assets release was written
against, and is guaranteed to be compatible with.
- Support for Blueprints (Flask 0.7).
- Fixed usage for incorrect request context during URL
generation (thank you, julen).
