v0.100.1 "fix ev"

minor fixes

• the autostop server (aka "watchdog"), when UI close : works better (it wait the 1st cnx before watching for suicide)
• the "ev" mechanism works well in all cases (see previous release bug)
• new manual_tests_event_0.100.1.py which tests all kinds of event bindings in one shot ;-) (todo: will be in selenium tests later)
