- (#15121) Improve string cut-off for locale table

- Patch #24183 by drumm: remove unnecessary setting from upload module.  Currently the upload module checks two max file sizes. First it checks a global option; if its too big it quits. Then it checks another max file size (or even sizes) related to the roles which a user is in.  We can remove the global option since the individual roles are checked.

  and fixed the node delete form to use a return destination.

  Generally improves readability; gets rid of technical jargon; provides
  concrete example; provides suggestions for how permissions can be used.

- Modified patch #18656 by Moshe: unifies the admin comment form and the usual comment form, similar to what we did for nodes. This resulted lots of duplicate code removal.

  Modifications: fixed breadcrumbs, tidied up delete confirmation page to be consistent with node deletions..

- Modified patch #20505 by Morbus: fixed scalability issues with terms, tried to create a better distinction between vocabularies and terms, fixed problem with term pager (temporary fix).
