include pivot options for dataquery

Use only one eml common stylesheet directory for all post 2.0.0 beta versions of eml. Point all eml versions to that directory in skin xml files.

include NSF grant number

use "prompt" xpath that matches current QTI serialization

handle case when there is a single question on the assessment

correct spelling of "Assessment"

change "blah blah" to something more respectable

add skin properties files so that first can be enabled as the default when configuring metacat in the admin interface.
note: not checking in the modifcation to metacat.properties file - that will remain a deployment-specific change and not included in the standard distribution
