Commit:	2337557a8c8a68db49013b30759be9ac8ca8135b
Message:	atusd firmware now supports setting the TST pin. - common/io.h: TST is connected to P0_7 - include/at86rf230.h: added test mode registers REG_CONT_TX_0 (0x36) and REG_CONT_TX_1 (0x3d), with their values - atspi/atspi.c (set_test_mode): set or reset TST and the LED - atspi/atspi.c (reset_rf): leave test mode - atspi/atspi.c (test_mode): enter test mode - atspi/atspi.c (main): flash the LED when in test mode - include/atspi/ep0.h (enum atspi_requests), atspi/ep0.c (my_setup): new command ATSPI_TEST to enter test mode - include/atspi/ep0.h (EP0ATSPI_MINOR): bumped protocol to version 0.1 - include/at86rf230.h: corrected comment before TRX_CMD field to indicate that the register is called TRX_STATE
