Runtime: Better handling of nested strings in spawn_subprocess commandline parsing

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.
