HPCC-10203 Add manifest resource support for wildcards and relative URLS

Resources can be directly accessed in WsWorkunits using the following url format:

/WsWorkunits/res/W20131016-193456/resourcepath/resfile.ext

i.e. http://ip:8010/WsWorkunits/res/W20131016-193456/abc/xyz/tryit.html

A browser should automatically follow relative paths in html files.

The manifest is accessible at:

/WsWorkunits/manifest/W20131016-193456

Also add support for using wildcards in manifest resource filenames:

&lt;Manifest>
  &lt;Resource filename="resources/*" recursive='1'/>
&lt;/Manifest>
