Fixed failed login lockout bugs by storing lockout time. Removed unused email verification expiration from admin UI.

Major whitespace cleanup of user report page; removal of redundant 'admin bar' that appeared on old administration pages; addition of "Bundles" to top "Administer" menu.

broken dependency on Guava 21.0-SNAPSHOT.

XNAT-4562, XNAT-4399, XNAT-4044: Changes to Spawner elements and JavaScript files to fix bogus rendering of investigators and to prepare for new User management UI.

Update for hashchange event to handle multiple hash parts - necessary to select a tab when page is loaded via ajax using the url hash.

XNAT-4242, XNAT-4399, XNAT-4400: a form that fails validation will show a dialog and stop submission; JavaScript components for updated table.dataTable widget that supports advanced HTML transformations and filtering; other JS updates to support changes necessary for new user management UI.

XNAT-4557 XNAT-4558 Added admin user and email to site admin. Fixed various handler methods to work better. Fixed issue where XnatAppInfo croaked when instantiated without manifest present.

notification preference change handling to SmtpHandlerMethod.

XNAT-4242: form validation errors will stop submission and display a dialog listing fields that need to be corrected.

XNATX-501: removed default 'Select' option from Spawner-generated menus; fixed an error with getting length of an undefined value; utility style classes: center/centered, align-left/text-left, align-right/text-right, nowrap/no-wrap; added 'sprite.png' file back to YUI folder - some YUI widgets still need it.

XNAT-4544: tweaked xmodal styles and defaults so buttons stay in the browser viewport and adjusted height of script editor dialog.

XNAT-4553 Allowed XNAT admins to configure auth providers via properties files in the config directory instead of just via properties files in plugins.

Removed styles for h1-h4 elements inside xmodal dialogs - these should be set elsewhere for the specific content.

XNAT-4533, more: Added Plugin Settings page - 'Administer > Plugin Settings' menu option will show when there's an installed plugin that has site-wide settings. The mechanism for this is clunky and could be improved if there was a way for plugins to register themselves as having site-wide settings. Split up items in 'Administer' menu for more granularity in inserting menu items. Other refactoring to support these features, including a new panel.form contentType option 'text/json' that submits JSON as text (needed for XSync plugin). (WHY!?)
