Display and filter on permisssion in lists

[Nicklas Nordborg]

This is very annoying when these listings are used for linking item A to item B. If the user doesn't have USE permission on item B a PermissionDeniedException is thrown when saving A. It would be better if the list displayed only those items that the user has at least USE permission for.

This ticket is now part of tickets #268, #269, #270, #271 and #272.

The infrastructure for this ticket is now in place. The most important change is the new setItemPermission() method on the EntityQuery class. With this it is possible to set the permission that is required for the logged in user.

I have tested this on the Labels list page, which can be used as a reference. In summary there are four changes that are needed:

1: Add an import statement:

import="net.sf.basedb.clients.web.PermissionUtil"

2: Add the 'mode' parameter to the method call that configures the query:

final ItemQuery<Label> query = Base.getConfiguredQuery(cc, true, Label.getQuery(), mode);

3: Add a new column definition:

<tbl:columndef
   id="permission"
   title="Permission"
/>

4: Add a new table cell:

<tbl:cell column="permission"><%=PermissionUtil.getShortPermissions(item)%></tbl:cell>

(In [2343]) Fixes #206: Display and filter on permisssion in lists

NOTE! This fixes the infrastructure only. The functionality still has to be added to individual pages. See the Labels list page for a working implementation.
