Unused views removal

[toskrip]

According to Tom these are removal view candidates:

WEB-INF/jsp/tags: all files in folder
WEB-INF/jsp/include/admin-head-prev.jsp
WEB-INF/jsp/include/breadcrumb.jsp
WEB-INF/jsp/include/showTerms.jsp
WEB-INF/jsp/include/sidebar.jsp
WEB-INF/jsp/include/userbox-inactive.jsp - already gone
WEB-INF/jsp/login-include/header-login.jsp - already gone
WEB-INF/jsp/login-include/login-sidebar.jsp
WEB-INF/jsp/managestudy/listSubject.jsp
WEB-INF/jsp/submit/initialDataEntry.jsp - probably

[constructum]

This view is also apparently unused:

WEB-INF/jsp/managestudy/listSubjectDiscNote.jsp

I don't know whether it is planned to activate it in the future, though.

If it is confirmed that it can be removed, then the whole servlet code and everything that depends on it, e.g. jmesa table code, should also go (see also #74 (comment) for more details).

[constructum]

Removed (with PR #468):

• WEB-INF/jsp/managestudy/viewEventCRFContent.jsp (view);
• ViewEventCRFContentServlet class
  (corresponding servlet; full path: web/src/main/java/org/akaza/openclinica/control/managestudy/ViewEventCRFContentServlet.java);
• all code related to the above (from classes Page and BreadcrumbTrail).

See also issue #466 for more details.
