Merge pull request #2 from knilsen/drum-text-changes

Text revision

Accepted pull request, though I see some problems needing correction.  Some files contain static urls to drum.lib.umd.edu instead of proper environment specific urls:

* dspace/modules/jspui/src/main/webapp/help/about_drum.jsp
* dspace/modules/jspui/src/main/webapp/help/about_submitting.jsp
* dspace/modules/jspui/src/main/webapp/help/permission_letter.jsp
* dspace/modules/jspui/src/main/webapp/home.jsp
