CNDA-478: Removed call to setID() that broke reference to target imaging session. The code changes for this jar are available at:

https://bitbucket.org/nrg/pipelineclient_1_6dev/commits/be27aa4efe28c29b81883127b309fbc6c39f3cde

The line of code that was removed was originally added to fix https://issues.xnat.org/browse/XNAT-2900, duplicate workflow entries on pipeline execution. Have verified
that code still functions properly with this line removed.
xModal improvement(?) - added jQuery object of current modal DOM element as a parameter for the 'beforeShow' method. Restored copyright info for jQuery Masked Input plugin.
Restored copyright info to some 3rd-party javascript files. (put the "fu" back in "function" on a couple, too)
