[Zope-CMF] [dev] CMF 2.2 dependencies

[yuppie]

Hi!


zope.app.component and zope.app.container are no longer part of Zope 2 
trunk, but CMF currently has many imports from these two packages.

All the code needed by CMF has been moved to new packages (zope.site, 
zope.browser, zope.container) that are part of Zope 2 trunk, but they 
are not part of Zope 2.11.


Possible solutions:
-------------------

1.) Make Zope >= 2.12 required for CMF 2.2 and change all imports.

2.) Make Zope < 2.13 required for CMF 2.2.

3.) Add zope.app.component and zope.app.container to CMF dependencies.

4.) Re-add zope.app.component and zope.app.container to Zope 2 trunk 
dependencies.

5.) Add a lot of try except imports and modify zcml files to make 
imports from both locations working.


Any preferences or better ideas?


Cheers,
