signup 5.x-1.1

NOTE: This will probably be the last release of the 5.x-1.* series, which will soon be deprecated. Sites should consider migrating to the 5.x-2.* series (especially once 5.x-2.6 is out).

Changes since 5.x-1.0:

• #321653 by shane_jordan: Fixed bug where if a signup administrator canceled an anonymous signup on a given node, all of that anonymous user's signups were also canceled. This bug was from the original implementation of anonymous signup support (#68497).
• #219680 by dww: Fixed bug where the email address of users who signup was being sent in the notification emails to event owners, which is an inadvertent disclosure of personal information. Now, only a link to the user's profile is included.
• #137609 by dww and stBorchert: Added a lot more themeability for how the site-specific custom signup data is displayed for the signed up user, the signup administrator, and in the email messages. This also fixes a bug (#178441) where the labels for the custom fields were not included in the email messages.
• #138401: drupal_get_path() not defined for anonymous users when caching is enabled. signup.theme is now included properly from hook_menu(), instead of global code outside any function.
• #202913 by westwesterson: Fixed ambiguous SQL query on the admin/content/signup page when using certain node access modules.
• #233512 by dww and tcocca: Added code to cancel all signups of users that are deleted from the site.
• #107136: Added $uid parameter to _signup_cancel hook (so it can be useful for something) and converted to use module_invoke_all().
• #249155 by joshk: Added the $user object as another argument when invoking hook_signup_sign_up().
• #160862 by adrinux and dww: Fixed paging on signup admin form (admin/content/signup) due to missing count query.
• #142402 by cpisto: Fixed SQL bug on PgSQL when event.module is enabled.
• #158688 by m3avrck: fix JS to work with aggregator.
• #179540 by dragonwize and dww: Restored the login/register links for anonymous users when viewing a signup-enabled node.
• #199383 by deviantintegral and dww: Fixed bug that could cause signup to invoke node_load() with invalid parameters on the node add form.
• #79331: Fixed inconsistent UI: Use 'Current signups' instead of 'Current Signups' since we don't capitalize individual words. Same for 'Cancel signups'.
• #259301 by dww: Fixed bug where the code assumes you want additional fields in your signup form. Signup now handles an empty return value from theme_signup_user_form().
• #247618 by selmanj and dww: Fixed bug where '... or register ...' was printed even on sites that have user registration disabled.
• #321463 by dww: Fixed UI bug where the 'Please login or register to signup' help text was printed even if regular authenticated users couldn't signup.
• #290740 by deviantintegral and dww: If 'site_mail' is undefined, use the 'sendmail_from' PHP ini setting as the fall-back value (Be Like Core(tm)).
• #322924 by dww: Fixed potential PHP error when generating the signup form resulting from an uninitialized variable.
• #328637 by dww: Fixed bug where error messages generated while validating an anonymous user's email address weren't translatable.
• #330281 by dww: Fixed broken link to the 'Signups' tab in the help text for the signup settings on the node form when creating new nodes.
• Fixed signup_install() not to force tables on MySQL to be MyISAM.
• #79332: admin/content/signup overview page was misusing tabs: now there's a status filter (much like the watchdog filter in core).
• #134557: Removed stale code and extra DB query from signup_sign_up_user()
• #135629 by hunmonk: Correct handling of Drupal.jsEnabled.
• #151342: Removed version from .info in CVS in favor of cvs_deploy.module
• Removed stale reference to "Flexinode" from the install docs, and added links to both CCK and Event.
• #168094 by dww: Improved comments for theme_signup_user_form().
• Numerous small code style fixes.
