XML-Print Webservice

Fixed two bugs, one with setting wrong document titles when creating new documents, and a NullPointerException due to the fact, that CRUD overwrites the MetadataContainerType-object inside the Holder.

Fixed a problem where tomcat did not return the POST content of a request if a parameter was accessed before the InputStreamReader was initialized.

added the following features and bugfixes: projectid typo, bg color for active tabs, border for active fragment/link, close button for tabs

For compatibility reasons with TextGridLab the metadata handler now returns an Object instead of a MetadataContainerType.
