Add low level function xschem reset_symbol, changed defaults in xschem: now toolbar and tabbed interface (more robust than multi-window) is enabled by default, doc updates, improved fix_symbols for setting/removing path compoents from symbol references, now uses low-level xschem reset_symbol (faster)
