XNAT-2429 XNAT-4201 XNAT-4423 Massive refactoring of libraries to get rid of split into root and application contexts. Moved lots of initialization from autowired fields to autowired constructors. Added method to create DICOM SCP instances without specifying ID since ID is now generated and provided. Fixed broken login on su operations.

XNAT-4421, XNAT-4422: tabs without groups now render properly; table rows are now properly appended to an existing table.

XNAT-4400, XNAT-4399: corrected stupidity in spawn.js changes; allow tabs to spawn without groups (madness!); changed method names of data tables and lists in panels to panel.dataTable and panel.dataList; some refactoring of XNAT.table methods - now subsequent rows will not contain more cells than previous rows.

XNAT-4142: script editor now works in all browsers; added "Script Label" column to listing and set label to copy id if left blank in the editor;

XNAT-4327 Removed additional code that set CSRF token. All token sets should now be done only in session event publisher at the point when the session is actually created.

XNAT-4399, XNAT-4400: Tables can be easily populated with a url - XNAT.table.dataTable('/data/url').table; form panels can use submission method from data-method attribute;  tab layout can not be specified in config object (rather than just through a JavaScript variable).

XNAT-4405 Added WWW-Authenticate to headers when non-interactive agent calls data URI. This lets non-preemptive basic auth work properly.

XNAT-4357 - Fix IE JavaScript issue in file uploader plus improvements to drag and drop and other minor uploader fixes/improvements

Minor refactoring of persistent and automation events. Better event listener exception handling and reporting. EventClass annotation is now an NRG processed annotation. Fix null Python scripting engine issue

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
