Make flash error (boot_v1.5.bin)

[larsfpeeters]

An error came up when I tried 'make flash'. The error read: esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: '/Volumes/case-sensitive/esp-open-sdk/ESP8266_NONOS_SDK_V2.0.0_16_08_10/bin/boot_v1.5.bin' make: *** [flash] Error 2

The file wasn't included in my SDK build anymore, only boot_v1.2.bin and boot_v1.6.bin.

To get this working I simply changed the line looking for this file in Makefile.ota to look for boot_v1.6.bin.
