Plone.reload

----------------

- Moved the template reloading support into an extra.
[hannosch]

- Added test_suite functions to the test modules.
[hannosch]

----------------

- Added CMF specific functionality: We support explicitly reloading all file
system based objects from skins folders while running in production mode.

----------------

- Avoid the `ENABLED` config flag and check against Globals.DevelopmentMode in
the browser view.
[hannosch]

- Make sure the import of the Globals module happens after the variable has
been set. This should make it compatible with Zope 2.10.9+.
[hannosch]

------------------

- Got the test coverage for the code reloading part up to 100%.
[hannosch]

- Fixed reloading of the module scope. The func_globals of functions is now
updated with new names introduced into the module scope, so adding new
import statements will work.
[hannosch]

- Specified package dependencies, added development buildout and added
extensive test coverage.
[hannosch]

- Figured out a way to support reloading code that uses decorators.
[hannosch]

-----------------

- Added the z3c.autoinclude entry point so that plone.reload is automatically
loaded on Plone 3.3 and above.

-----------------

- Do not remove attributes from classes when reloading. ZCML directives and
other wiring is liable to add attributes to class that will then disappear
on reload. This means that if you have removed a class attribute, it will
*not* disappear on reload. In this case: restart. :)
