[tools] Fixed iterating through the available hex files
Removed trailing spaces
Fixed bug in reporting IOERR_COPY. test_all_result was not filled with IOERR_COPY error when using -n ooption with single test
Changed console object name from 'console' to something more unique like 'mbed_cpputest_console'
Added new switch -u. Now you can force test suite to shuffle test execution order so your tests are executed in random order
Added simple checks to make sure assertions outside test runs don't crash
Added new switch -V which will allow users only to print test result text from serial port during test. It helps just to see test results from test / host test itself
Merge pull request #404 from xiongyihui/master
