Some statusbar shrinking

I'm thinking of adding in something that checks which network devices
are up and puts both of them in the status bar, hiding inactive devices,
also showing the signal strength and access point for wifi.

0.3.0 release

 * Fixed all memory leaks
    Valgrind shows that everything is free and clear
 * Cleaned up the statusbar length (may be a bit too small now, though)
 * The warnings when compiling with -Wall are now fixed
 * Added in some initial auto-network-switching in there
 * Changed NET_DEVICE to NET_DEVICE_PRIMARY

If you notice any issues, please report them. Thank you!
