plotcontroller: add method to get the current plot full file name and the current plot folder full path from Python script.

gen_gerber_and_drill_files_board.py: 
 * fix to make it compatible with rev 6280.
 *  allow this script to create files in  the current plot folder defined from the board forder, no more only in current working directory.
