signup 4.7.x-1.1

After many months of unfortunate neglect, the singup.module has recently gotten a round of major attention and improvements. Mostly, the changes below are bug fixes, but in a few small cases, some new functionality was added, as well. This release includes a database update, which renames the permissions this module uses, so be sure to run update.php on your site, and then visit your 'access control' page (at /admin/access) to ensure the signup-related permissions are valid for the roles defined on your site.

Major since 4.7.x-1.0:

• #91284: signup.module doesn't respect privacy: db_rewrite_sql() missing
• #91284: signup_conflicts.module doesn't respect privacy: db_rewrite_sql() missing
• Major permissions, UI and usability fixes (includes a DB update):
  • #69367: Turn the "Users can view signups" setting into a permission.
  • #69283: Rename all other permissions to be more clear, consistent, etc.
• #49007: Fix all the UI bugs and weird behavior about enabling and disabling signups per-node-type and per-node.
• #102949: For consistency, allow the %info token in reminder emails, too.

Other since 4.7.x-1.0:

• #126942: Add "Reset to defaults" on settings page.
• #104804 by hunmonk and dww: Fieldsets are now supported in the customized signup form. The code should now handle nested values regardless of depth.
• #67067: Required fields and default values on signup form. Inspired by a patch from pjdevries. Also cleans up the formatting of the $form array in this function, vastly improves the doxygen comment, and includes a step in the INSTALL.txt file about customizing this form.
• #125705: Make comment in signup.theme about not touching the definition of $form['signup_form_data']['#tree'] even more clear.
• #123648: Fixing improper use of links in watchdog() messages
• #78559: Fixing numerous bugs in signup translation:
  • incorrect use of format_plural()
  • badly formed t() strings with HTML and other goo inside
  • wildly stale (and sometimes missing) .pot files
• #69372: Ported signup to use theme('username') for user links
• In the (evil, hard-coded) HTML for displaying signup information on user profile pages, we were leaving an H4 open by accident.
• l() calls check_plain() for you, so we were double-escaping output.
• #107154: Fix signup_sign_up_user() to prevent the same user from signing up more than once for the same node.
• #128021 by adrinux: Convert html br to xhtml and use strong instead of b
