Shapely 1.2.15

Shapely 1.2.5 is out: http://pypi.python.org/pypi/Shapely/1.2.15. This release is mostly concerned with helping packagers downstream. Changes:

• Eliminate numerical sensitivity in a method chaining test (Debian bug #663210).
• Account for cascaded union of random buffered test points being a polygon or multipolygon (Debian bug #666655).
• Use Cython to build speedups if it is installed.
• Avoid stumbling over SVN revision numbers in GEOS C API version strings.

There is a growing list of features in GEOS 3.3.x that Shapely isn't accessing yet and I'm looking forward to getting to these later this summer.
