Fix assets syntax errors

[radanskoric]

Some css files are using:

filter: alpha(opacity:50)

That is incorrect css syntax. Instead, "opacity=50" should be used. If assets pipeline is enabled with Sass compiler it will throw an error during rake assets:precompile task. For example that prevents a project that uses it to be deployed to Heroku.

This pull requests fixes those occurences of opacity filter.

Is there something I can do to get this merged in? Is there something wrong with the changesets?

Thank you in advance.

+1 for this patch

Please merge, otherwise this plugin is rather unusable on production systems where the assets need to be precompiled. The precompiler fails awfully because of the syntax errors.

Thanks!
