adjusted obp/tooltip module object references to avoid undefined objects due to load time uncertainty
added license/ dir to oxygen project file
updated project pathing to use uri.js

Project path resolution, which is done at boot-time in the
openbibl.boot.xsl stylesheet and in the js/openbibl/download.js
module, is updated to:

- use URI.js for simplifying absolute/relative path determination
  and for forming absolute paths
- during "boot from xml" stage, construct absolute paths for
  the openbibl resources
- during "serialize/download to HTML" stage, update JS resource
  paths to absolute paths, to enable the HTML file to reside
  in locations other than the XML file directory, if necessary
added async flag to opb/config module serialization; reverted async flag value to true
added absolute-url update to @data-main and @href attributes in obp/download module
fixed json-file retrieval path in obp/query module
