hierarchical_select 7.x-3.0-alpha4

Highlights of this release (which quickly followed alpha 3 and hence lists changes in alpha 3 as well):
- only one known remaining bug: #1242812: Previewing nodes deletes term reference values
- fixed major bug: multiple HS widgets on the same page could collide with each other
- save_lineage support
- create_new_item support
- upgrade path!
- HS Menu support
- fixed #required support
- fixed i18n support for HS Taxonomy
- fixed import & export

Make sure that you know if the part of Hierarchical Select's functionality that you want to use has been ported. Otherwise, you may be in for a frustrating upgrade experience.
See the included TODO.txt file for details. In a nutshell:
- Taxonomy support is almost complete, only "entity count" and token support are missing
- Forum support has **not** yet been ported (but relies on Taxonomy, so this is trivial)
- Taxonomy Views support has **not** yet been ported
