Remove notes about -doc-title and -doc-version not being used

Confirmed these options are used by editing build-ant-macros.xml and viewing
the output,

               <scaladoc docRootContent="${src.dir}/@{project}/${@{project}.docroot}"
                 destdir="${build-docs.dir}/@{project}"
-                doctitle="${@{project}.description}"
+                doctitle="${@{project}.description} - test-title"
                 docfooter="epfl"
-                docversion="${version.number}"
+                docversion="${version.number} - test-version"
