V2.0.1

This is the version number of the first commit done since Eric handed off development of the directory, and due to the small number of changes made to the directory made in between, it seemed prudent to call it 2.0.1 given Eric's last commit was truly version 2 of the application. This version of the application contains changes to the advanced search on the directory page, so that the search would retrieve the same results as the advanced search when browsing through users. This also contained a rake function for importing student id numbers in batch format to update students in the directory. Similar functions for other user information was also added, so that batch updates can be done based off of netIDs. The to_csv plugin is broken at this time.
