Enhanced the Makefiles to consistently use the BUIDDIR variable.
updated all file headers to 2019
Updated AMiRo-BLT submodule and implemented support of the the newly introduced /dev/ttyAMiRo<ID> serial port alias.
1) enhancements of the makefiles: - replaced all absolute paths by relative paths - include directories now consistently do not have a trailing slash - it is now possible to specify a custom build directory by setting the BUILDDIR variable - updated C/C++ standard to C11 and C17 respectively (igrnore warnings caused by ChibiOS for now)...
Major overhaul to AMiRo-OS version 2.0.0
