Uncommented the line adding a method attribute to a Spawner form element

XNAT-4268: set window.loggedIn variable to true in popup templates - the user must be logged in to view the popup anyway.

This reverts commit e81ae59b.

XNAT-4346 XNAT-4330 Changed AbstractXnatRestApi to AbstractXapiRestController. Fixed logic in permissions check that broke certain saved searches.

XNAT-4399: updates for XNAT.table widget and new XNAT.ui.panel.data.table widget; also fixes for sorting.

XNAT-4248 - passwordExpirationType should be a set of radio buttons, plus calendar date picker and style changes to support V&P icons

XNAT-4239 Removed rarely used data types. Added PETMR to AdminUI. The PETMR split option is not working right for me, but I think it's because of existing windows prearchive bugs. Otherwise everything seems to work correctly.

Enable tab selection on page load with the url hash; added 'onRender' method for Spawner widgets - fire callback functions after widgets are rendered; other minor tweaks.

XNAT-4368: make ANY table with a header sortable by simply adding 'sortable' class to the <table> element or 'sort' to a <th> element.

XNAT-4373 Changed references to the XftStringUtils method IsAlphaNumericUnderscore() to isValidId().

XNAT-4318: removed 'loading' dialog since data is loaded so fast; also preserve tab selection on load and reload of admin page based on url hash.

XNAT-3846: disable login from IE 8 and show error message prompting usage of a newer browser; normalized property names in spawner.js; other minor JS tweaks to fix things IE was choking on.

XNAT-4333, XNAT-4345: Reorient admin page layout with stacked labels and inputs to provide more horizontal space.

XNAT-4186 Fixed session registry so users get warnings if other people are logged in to their account again.

XNAT-2299,XNAT-3977 Removed nonfunctional view edit script page since it hasn't worked in a while and everything it provides can be done elsewhere. Future enhancements to script editing should be done in the AdminUI and in something other than qooxdoo.

XNAT-4303: tweaked horizontal positioning of prearchive ui; tweaks to styling of prearchive details page; fixed reference to jquery-migrate script in 'Noninteractive' template.

Updated jQuery 1.x and jQuery migrate scripts; removed jQuery 2.x files since they weren't used; changed name of 'chosen' menu functions to a more generic name for future transition to another menu widget.
