Subject: [PATCH] make_css_data_uri: support @-moz-document regexp(...)

The keyword argument $regexps allows the caller to supply one or more
regular expressions (as strings or RegExp objects), to be used in the
constructed stylesheet @-moz-document regexp(...) specification.
@-moz-document regexp(...) was added in XULRunner 6.
