added attributes spice_ignore=short, verilog_ignore=short, .... that will transform the instance into a short in the current netlisting mode, shorting all pins to the same net. Works similarly as lvs_ignore=short, but does not need lvs_ignore global setting

Place polygon bind key is now `p`, ctrl-w is now `Close current schematic`, while ctrl-q is `Quit xschem`. Reorganized File menu, added more orthogonal `Create new schematic/tab` removed some largely unused entries. Ctrl-w does not close the last window, just leaves it blank. Use ctrl-q to close xschem
