Rt.bulkmodify

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

- Version 0.4.1 was providing a bad setup handler target
[keul]
- Fixed UnicodeDecodeError when the extracted text for preview contains
non-ASCII chars. This close `4`__.
[keul]
- Add Portlet Replacement code
[do3cc]
- Find text language independent
[do3cc]
- Work with unicode everywhere. This should not be a bigger problem, but if you
wrote custom ``IBulkModifyContentChanger`` adapters please have a look at the
interface, you must provide the new ``utext`` property.
You can have a look at the existing adapters on how to extend your adapter.
The behavior of existing attributes did NOT change.

- When performing searches, display immediately the "loading" info,
not after the first completed request
