Updated version to 1.7.1-SNAPSHOT. Converted nrgxnat.artifactoryonline.com URLs to nrgxnat.jfrog.io.

Added support for retrieving current theme from REST. Added theme service as bean accessible from JSP context. Made accessible beans easily configurable from the configuration.properties file. Added ability to define programmatic transform classes for database migrations. Defined the themeService bean for xnat.tag.

Changed signatures of List<UserI> methods, added checks on SystemPathVerification to make sure the system is REALLY initialized. Added fix for AliasToken serialization issue. Made warning about 1.7-compatible rt.jar more explicit and more helpful.

Checked for allowDataDeletion ahead of template population. If true, don't populate template because you don't want to restore those values.

XNAT-4242: Validation type that would *optionally* allow empty fields, would instead *require* them to be empty.

XNAT-4242: Form validation methods seem to be working well, but errors are only highlighted - form submission is not blocked; updated Site Admin YAML with validation hooks.

XNAT-4463 Added message in cases where no project owners have valid emails. Hacked the UI to show this as an error message using Will's string contains hack. Hopefully we can get a better way to handle message type soon.

XNAT-4463 Made PAR requests not fail when one project owner had an invalid email (also prevented similar failures on PAR acceptance/denial).

XNAT-4516 Added better task tracking and logging to initializating task executor, added automated completion and execution tracking, logging and messaging. Broke view creation/update code into stand-alone initializing task. Added check for table that gets updated so that queries don't error out.

XNAT-4399, XNAT-277: Fixed transformation of table cell content; added links to projects of which investigators are PIs.

XNAT-4399, XNAT-4242, XNAT-277, XNAT-1365: added hooks for validation and fixed some validation methods; updated codeEditor to handle read-only code blocks (for use in plugin inspector); added UI for managing investigators; improvements to table.dataTable widget for plugin registry and investigator tables.

text/plain content type or ambiguation with multiple return types.

XNAT-4518, XNAT-4520: included missing scripts on Noninteractive.vm template; checkboxes (and switchboxes) can use 1/0 for checked/unchecked as well as true/false.
