Import errors with GAE 1.6.4 on dev_appserver startup

[aburgel]

it looks like some changes in GAE 1.6.4 broke how djangoappengine starts up when running locally.

djangoappengine mimics dev_appserver's module sys.path behavior, it add almost everything in SDK_ROOT/lib/ to sys.path following a simple heuristic. this no longer works because there are now two versions of webob, one for python2.5 and one for python2.7.

the simple fix is to check which version of python is running and add the right webob path. the better fix is to rely on dev_appserver to set sys.path, so we no longer have to keep up with their changes.

i'll put up the simple patch in a bit, it might take longer to get the more complicated one working, if its possible at all.

this is the exception in case anyone else runs into it.

I edited your comment to wrap the traceback in a code block.

this is mostly fixed by #24 but i think we could use a long term fix, so i'll leave this open.
