- Patch #393406 by michaelfavia, Freso, catch, stBorchert, David_Rothstein, ksenzee: improve role administration page.

- Patch #581760 by yoroy: by default, don't center-align the user login form in the block. It is still center-aligned in Garland.

#382870 by geerlingguy, jmburnz, EclipseGc, JohnAlbin, sun, et al: Update and Polish default node.tpl.php output.

  The access rules capability of user module has been stripped down to a
  simple method for blocking IP addresses. E-mail and username restrictions
  are now available in a contributed module. IP address range blocking is
  no longer supported and should be done at the server level.

  This patch is partly motiviated by the fact that at the usability testing,
  it frequently came up that users went to "access rules" when trying to
  configure their site settings.

- Patch #30984 by webchick, keith.smith, kkaefer, Crell et al: provide descriptions for permissions on the permission administration page.

#145737 by yhager, documentation cleaned up by myself: add support for RTL CSS overrides and default RTL CSS override files for modules
Note: properties, which are different in the RTL display are marked with /* LTR */ in default CSS files now,
so maintainers remember that changing them should also have an effect on RTL CSS files.

This should open the way for better RTL (right-to-left written) language (such as Arabic and Hebrew) support.

- Patch #144859 by dww: added optional e-mail notifications when user are approved, blocked, or deleted.
