ANN: cssutils 0.9.8a1

[Christof]

what is it
----------
A Python package to parse and build CSS Cascading Style Sheets.
(Not a renderer though!)


about this release
------------------
0.9.8a1 is an early alpha release. Please note the *major* changes in 
the css value API.


main changes
------------
+ **API CHANGE (major)**
     replace CSSValue with PropertyValue, Value and other classes.

     NEW CLASSES:
         :class:`cssutils.css.PropertyValue`
             replaces CSSValue and CSSValueList

             - is iterable (iterates over all single Value objects which 
in soruce CSS might be separated by "," "/" or " "
             - a comma separated list of IDENT values is no longer 
handled as a single String (e.g. ``Arial, sans-serif``)

         :class:`cssutils.css.Value`
             replaces CSSPrimitiveValue with separate ``value`` and 
``type`` info (value is typed, so e.g. string for e.g. STRING, IDENT or 
URI values, int or float) and is base class for more specific values like:

         :class:`cssutils.css.URIValue`
             replaces CSSPrimitiveValue, additional attribute ``uri``

         :class:`cssutils.css.DimensionValue`
             replaces CSSPrimitiveValue, additional attribute ``dimension``

         :class:`cssutils.css.ColorValue`
             replaces CSSPrimitiveValue, additional attribute ``red``, 
``green``, ``blue`` and ``alpha``

             **TODO: Not yet complete, only rgb, rgba, hsl, hsla and has 
values use this object and color and alpha information no done yet!**

         :class:`cssutils.css.CSSFunction`
             replaces CSSPrimitiveValue function, not complete yet

         also renamed ``ExpressionValue`` to 
:class:`cssutils.css.MSValue` with new API

- IMPROVEMENT/CHANGE: Validation of color values is tighter now. Values 
like ``hsl(1, 2, 3)`` do not validate as it must be ``hsl(1, 2%, 3%)``. 
This mostly effects HSL/A and RGB/A notation.

- **IMPROVEMENT**: New Value parsing and API accelerate parsing of style 
declarations which take about 20-30% less time now. Of course this 
depends on the complexity of your styles.

+ BUGFIX: fixes issue #41, #42, #45, #46
     PropertyValue.value returns value without any comments now, else 
use PropertyValue.cssText

- FEATURE: ``cssutils.replaceUrls()`` accepts as first argument a 
`cssutils.css.CSSStyleSheet` but now also a
     :class:`cssutils.css.CSSStyle
