* 2.9.1-svn-15
 
 * fixed JSPWIKI-757 Have default file direction location be in relative directory instead of 
   hardcoded /p/dir1/dir2.If jspwiki.fileSystemProvider.pageDir in jspwiki.properties isn't
   provided, it will default to ${user.home}/jspwiki-files
   
 * new API package org.apache.wiki.api.engine, intended to hold WikiEngine, its managers and
   related classes. FilterManager and PluginManager moved there (cfr. JSPWIKI-155, JSPWIKI-303
   and $SVN/trunk/doc/2.10-API.txt).
 
 * org.apache.wiki.FileUtil and org.apache.wiki.TextUtil Moved to equivalent classes under 
   org.apache.wiki.util. Original classes marked with @Deprecated and forwarding to the new 
   ones until 2.10

 * deprecated WikiEngine.getRequiredProperty( props, key ) in favour of 
   TextUtil.getRequiredProperty( props, key ). The former will be deleted in 2.10 scope
