Openmeetings UI

[rmw-89]

Hi. I'm using Openmeetings in my work. It's very good webconferencje 
application. I need to do some changes in UI. I tried to delete some things 
from Login Page and I found good lzx. I did it and it's work. Next thing which 
I want to do is change OpenMeetings MenuBar for user. I want to delete some 
option in MenuBar e.g. Recording, Rooms. Can someone help me to find good LZX 
or tell me how I can do this changes. I want to set default pages to Calendar.
 
Best Regards
