Tests: Enhance robustness of stdout driven waiting state in Sikuli based tests.
Some tests were randomly passing, because from time to time waiting for idle was skiped. It was combination of multiple problems :
- buffering on stdout (now use readline + flush for each write to log)
- it is sometime required to wait for activity before waiting for timeout added "WaitForChangeAndIdle" to "stdoutIdleObserver"

Mutlistateh widget hides all subelements whose label do not match given
variable value representation. For exemple if given variable type
is HMI_INT and value is 1, then elements with label '1' will be displayed.
Label can have comments, so '1#some comment' would also match. If matching
variable of type HMI_STRING, then double quotes must be used. For exemple,
'"hello"' or '"hello"#another comment' match HMI_STRING 'hello'.
Click on widget changes variable value to next value in given list, or to
first one if not initialized to value already part of the list.
