I have changes on a branch, 'tseaver-typeinfo_as_apb-branch', which
modify the TypeInformation objects to derive from ActionProviderBase,
and therefore manage lists of ActionInformation objects rather than
dictionaries (just as the tools do).  Chris and I talked about making
the equivalent change to the ActionInformation instances:  they would
expose an additional "propertysheet-like" interface for setting
arbitrary additional data.

We should also add a "first-class" property to ActionInformation for an
icon, as this will be generally useful in lots of places.

I plan to merge this branch *after* the 1.3 release, unless I get
significant feedback that it is OK (works with Plone, with other custom
add-ons, etc.) Real Soon Now (tm).
