Fix security hole: any registred user was able to execute curation tasks

As the curation servlet is mapped on both paths tools and dspace-admin a smart
user could take advantage of the form parameters reserved to the main admin
console and redirect the request to the tools path. The main admin console need
to enforce security directly without rely only on the administrator filter

DS-402 Performance and UI improvements for itemmap

This commit remove hardcoded reference to the author index for both discovery
and lucene provider. The admin is now able to perform a generic search or choose
from one of the customized indices or filters.
A very simple pagination, only next and previous buttons, has been introduced to
avoid performance issues with large result set.
Finally has been introduced optimization to perform the "Not owning collection"
check and, limitly to discovery, authorization check directly as part of the
search.
