added -u to avrdude erase call to disable safemode. It is necessary
because avr109 is not able to read nor write fuses and avrdude exited
with code 1.

Enables to store the config .yamls in the source dir.

Upload for each test executed makes more sense.

files not found. Minor formatting.

additional option 'workdir'  in suite config allows to change this location

tools/profiling: replace all occurrences of '$MYDEVICE' in CFLAGS with id of device 'mydevice' if defined

Added braces to highlight test and device names in log output.

- node configuration is usually independent from test configuration
- we might also want to aggregate multiple test directories to a full test suite
Thus a setup with 3 different config file types (nodes, tests, suite) is reasonable

New config option 'repeated' allows to force multiple runs of the same test.

This makes it possible to work also with an incomplete node set.

With the option one can add text to the graph label

The address in the AVR is given in words not in bytes. Previously the
script handled conversion, but doing it in Contiki should be cleaner.

This way we can still record useful debugging information like reset
reason.

Supply contiki as testcase classname as jenkins doesn't play nice with
an empty name

There was a problem where the test wouldn't retrieve all queue items
after all the threads were finished. This resulted in some of the
reports missing from the logs.
