Add:osd/core:

- added the possibility to set attributes of OSDs runtime
- added navit command for setting attribute of a named osd 
- added the possibility to set src attribute (background image) of osd buttons runtime
- created "command interface" osd type to be able to access command system accessible data (for example route_status) and display it either as text or image (see Ticket #815 for details)
