Using the new checkIsMyActiveRole check where necessary.

Added checkIsMyActiveRole check to the access module.

Make coverage conditional on run.py flag Coverage can now be enabled by running './run.py --coverage'.

Manually call start and end in test_sidebar Since we are not using a request directly we need to manually do the set-up and tear-down required.

Use request.start and end Without the start and end we die on 'assert self.in_request' in the core per request value store methods.

Add a start and end method to MockRequest

Added tag v0-5-200913 for changeset 55adeea795ab

Set new Melange version number to 0-5-20090913 in app.yaml.template.

Changed the conversion starter system to an update starter system. Also increased the usability of the update page by adding more information abou t each update that can be done and for which version number this applies.

Use the new optional argument to endRequest in the middleware Currently endRequest is called twice on an exception if Django intercepts the exception and returns it's own result. By setting optional=True we do not crash on 'assert self.in_request'.
