ALF-19700 BM-0013: Soak: V420b227_03: Transformation server overloaded

- Modified the way content.transformer.<transformer name>.extensions.<source>.<target>*.*.supported=[true|false] work
     so they are still backward compatible AND one can define if unmatched mimetypes are supported or not. For example:
     content.transformer.remoteServer.extensions.*.*.supported=false
   - Added properties to transformers.properties so that the Transformation server ONLY supports the transformations
     it did in 4.1.5 AND allows customers to change just one property to allow the Transformation Server to do all 
     transformations that it can with the exception of those that go to text, as generally the default transformers do
     a better job and are faster.
