- fix for OODT-665 CAS RDF and RSS product service doesn't allow product type met to have keys with spaces
  - updated RDF and RSS services to test if there is white space in a product type met key and if so:
     a) split the key string on whitespace; and then use WordUtils.capitalizeFully to turn into CamelCase and StringUtils.join to combine
     b) examine the value string and use StringEscapeUtils.escapeXml
  
  -also did this for the new JAXRS services (Ross L please make sure I got this right)
  
  I tested this on some keys within the context of my DRAT project on Github http://github.com/chrismattmann/drat/ and it worked great.
