Porting document type-based submission to JSPUI
Clean up dspace-api doc comment warnings
Clean up doc comments in JSPUI, XMLUI
Clean up doc comments in SWORD, XOAI, and one more in XMLUI

Delete leftover debugging output
Revert a little more reindentation

Rename the property default.dspace.dir to  dspace.install.dir
