template::adp_include does not reset the adp_level to the previous one. so, in case of nested adp_includes, the adp_level is incorrect leading to strange errors. i fixed this only for xowiki.
Added two package parameters: RichTextEditor (values "rte" or "xinha") and XinhaDefaultPlugins (list of plugins to be used per default, when xinha is selected)Per default the behavior is unchanged, rte is used.
adding limitation to attribute search condition type so that only attributes the user has read permission on for this package instance are returned as search options
