dvb: Remove the idlescan feature
dvb: Don't do initial scan on startup
dvb: Remove tdmi_got_adapter and tdmi_lost_adapter (unused)
dvb: Remove tdmi_time (unused)
dvb: Make sure to remember initialscan after restart
webui: Upgrade CheckColumn to extjs 3.4
Fix DVB URI /dvbnetworks -> /dev/locations
Remove unused Ext.grid.RowExpander
DVB networks view, WIP
dvb: Add dvb_network_t and start to migrate stuff there from dvb_adapter_t
More members to dvb_network_t
Move mux configuration stuff into dvb_mux_t

This also disables sat_conf stuff (LNB switches, etc) but we will
have to solve that in a different manner anyway
Remove unused tdmi_satconf_link
Move more code from th_dvb_mux_instance_t to dvb_mux_t

  uint32_t dm_network_id;
  uint16_t dm_transport_stream_id;
  char *dm_network_name;     /* Name of network, from NIT table */
  char *dm_default_authority;
Move some table stuff over to dvb_mux_t
Migrate tables into dvb_mux.

Also let some parts of the tuning work with dvb_mux
Moved almost everything out from tdmi
dvbreorg WIP

Initial scan now works again

We have a new idnode system that can give an entity a UUID which then can
be looked up externally (webui, etc). Good when browsing stuff
The UUID is supposed to be persisted on on disk when saving enteties
dvbreorg: Various refactoring
dvbreorg: Service subscription now possible
