FIX import issues: Description field not set
FIX html <base href="{$rootWebSite}" />

DEPRECATED: getServerRootURL()
this method causes big trouble when using CodevTT

this method is also responsible for the 'subdirectory install' problem
(installing CodevTT in a folder named '/var/www/html/tools/codevtt' fails)
