implement topmenu in idots template set
add idots preference to enable topmenu
add idots preference to disable general sidebox menu
some cleanups in idots framework class
some cleanups in egw_framework
- virtual baseclass egw_framework in the API which each template extends
- replaces $api/footer.inc.php, $tpl/head.inc.php & $tpl/navbar.inc.php
- all existing phplib template sets just inherit the idots_framework, but can have own templates
- moved most html from navbar.inc.php into the navbar.tpl
--> idots & jerryr are reworked and working, all other template sets are disabled at the moment
--> The rework was done to add a selectbox to add all sorts of entries without the need to change to the app first. This is now implemented in the egw_framework class using the link-registry.
- lay-out fixes in header
- background in loginscreen to make it a little less boring
- IE fix for wrong z-index with Selectboxes: temporarely hide selectboxes when showing menulayers
- extra option to disable IE png fix
- extra option to choose Click or Mouse Over to show menu's
- extra option to auto hide sideboxmenu's (a lot of people will like this)
- extra option to use sliders for showing menu, default enabled (see testresults below):
Mozilla-firebird Windows -> OK
Mozilla-firebird Linux -> OK
Internet Explorer 6.0 Windows 2000 - OK
Konqueror 3.1 Linux -> gets very slow, lay-out bugs (don't use this option with konqueror)
Opera 6 Linux -> showing works, hiding not, lay-out bugs (test again please)
Opera 7 Linux -> very annoing bug with temporarely hiding selectboxes (must not be hard to fix, pathes are welcome)
please also test this with Safari, Mac IE 5, Win IE 5.0 and 5.5 and report bugs at sf
