Add Arduino compatibility layer We can now directly compile arduino sketches (.pde) files. Arduino compatible analogWrite works now. But there is still a long way to go, serial I/O and timer stuff (delay, millis etc) currently don't work (not tested but I don't expect this to work). It can be used in an arduino sketch or in a normal contiki program. We get a PWM frequency of 490.2 Hz (a period of 2.040 ms), that's Arduino compatible. If you need different frequencies see native timer usage in examples/osd/pwm-example In a contiki program you have to call arduino_pwm_timer_init to initialize the timer before pwm works. The arduino sketch wrapper already does this. For running a sketch, see examples/osd/arduino-sketch

Factor resources, fix time Now there is a generic resource that can generate and parse application/json as well as text/plain. It can be re-used, only the from_string and to_string routines have to be written and the resource properly set up. A new resource format is specified, see GENERIC_RESOURCE in, e.g., examples/osd/pwm-example. This is now used in all my examples, namely pwm-example, arduino-sketch, wallclock-time. There was an off by one error for the month in time formatting (in gmtime and localtime). And the leap-year computation was broken. Both fixed now, so we get a correct date. For localtime we are still 2 hours off because daylight saving isn't implemented yet. Also renamed gmtime to utc.
