[WWcvs] webwork2: When viewing a file-based problem library, don't show to problem library's prefix in the "select a problem

[Sam H. v. a. <we...@ma...>]

Log Message:
-----------
When viewing a file-based problem library, don't show to problem 
library's prefix in the "select a problem collection" popup. This can 
significantly shorten the length of the options in that popup, making 
them more managable.
