[MOD]Removed namespace option from the wiki environment screen, since it's an advanced option (it will come back in a new advanced screen in short). Replaced by options related to Wiki structures, which are more common for basic sites and come disabled by default. Wysiwyg screen shown (when enabled) before textarea screen.
