[platform-ui-dev] Activities update

[Kim Horne <Kim_Horne@xxxxxxxxxx>]

There have been several changes to the
activities support in the workbench in the past few days.  Most of
these changes are cosmetic.  The  'Show All'/'Raw' tabs have
been removed in favor of a 'reveal' check box that toggles the filtering
state.  Additionally, if you've chosen to reveal hidden items then
these items will be highlighted.  

The remainder of the changes have been
to the API.  The above mentioned 'reveal' option may now be suppressed
by the product manager by setting the IWorkbenchPreferences.SHOULD_ALLOW_SHOW_ALL
preference to false.  In this mode the user would only ever be able
to see items that are enabled by activity filtering.  We have also
given the product manager the ability to enable an activity by default.
 This may be accomplished by using the <defaultEnablement id="foo"/>
tag in the activities schema.

The activities web page (http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/platform-ui-home/activities/index.html)
has also been spruced up by Tod and myself.
