Handle case when com.recomdata.searchtool.identityVaultURL is undefined

When assigning com.recomdata.searchtool.identityVaultURL to a String
variable, java.lang.Object.toString() is called (not Groovy's special
handling of toString() for Maps) and the result is something like
"groovy.util.ConfigObject@4ef2a6dc".
The test for whether this variable is defined is testing it for length
larger than 5, which will always be true when it's not defined. Fixed by
assigning to an untyped variable (def) and testing its truthness before
checking the length.
Declare some image resources so they don't 404

This would not be necessary if all the image references went through
<r:img>, ${resource()}, etc. But some don't as the <img> src is changed
via jQuery. Worse, this is done on fully resolved URLs, which include
/static/. The result is that the "legacy" resources paths in the grails
resource plugin are never hit (they would be hit if the URL request were
/image/foo.png instead of /static/image/foo.png, as the legacy resource
filter is set to intercept '/image/*' by default), so grails has no
chance to create the undeclared resource and a 404 ensues.

Fixed this by declaring the image resources in a resource module.

Remove code related to old SSO implementation
Add helper script for callback debugging on V8

The script is only included in the dataset explorer with the following
configuration setting:

	com.recomdata.debug.jsCallbacks = 'true'

When an exception occurs inside a callback function provided to one of
several builtin functions (like XMLHttpRequest.send()), the stack trace
will be printed to the console along with the stack trace at the point
the callbacks were registered.

Currently does not support removeEventListener() methods.
