Fixed few bugs and changed the formatter and widget types to define() consts. Added a field cache clearer so that radioactivity can be seen on the edit page as "live" (this needs a work around though)

D7 fixes here and there. Made admin ui path a defined var so that it can be changed easily in the future. Emissions now "work"

- Implement 'node view by authenticated user', which gives energy only for
  authenticated node views.
- Add comment_publish energy also for auto-approved submitted comments, as
  one could logically expect.

This commit is related to issue #452288.

  belongs into radioactivity.inc
o Clean _radioactivity_possibly_remap_id(). It used to produce notice
  because of access to unset field in radioactivity_info array

- After profile delete, go to profile list page
- After new profile save, go to that profiles edit page
- Profile id sanity checks in profile edit and profile delete
- Profile list page: display 'No profiles defined' in the profile list
  if no profiles defined

- use abs(energy) < cut_off as a cleanup criteria  (was just energy < cut_off)
- don't run cleanup for profiles where cut-off is disabled

and radioactivity_http. Their porting will have to be done at some
later time.

- radioactivity_comment: register also radioactivity_node_views_handler_sort_left_or_inner
  This makes radioactivity_comment views support work without radioactivity_node enabled
- support for choosing LEFT/INNER join in sorts
- LEFT JOIN sort case: use COALESCE($energy, 0) to ensure that NULL is considered as 0
  when sorting

o rename _radioactivity_get_decay_profiles()
       => radioactivity_get_decay_profiles()

radioactivity-admin-ui.inc
o make _radioactivity_prune_array() prune more

radioactivity_debug module:
- port to D6

lacks the handler support to choose LEFT/INNER join for sort.

o Use correct votingapi callback, it is:
  <module;>_votingapi_insert(...)

Side note:
o radioactivity_votingapi used callback <module;>_insert(...). It
  worked because that actually matched module <code>radioactivity</code> which is a dependency
  for radioactivity_votingapi. However, using same pattern for
  <code>radioactivity_up_down_voting</code> obviously missed
  the votinga callback... Hope we got this right this time!

o Introduce radioactivity_up_down_voting module
o Fix some radioactivity_votingapi descriptions

to radioactivity.inc. Utilize radioactivity.inc in radioactivity_node.module.
This is a fix for issue #301230.
