sqlite: harden multithreaded queries
small fixes

-just small fixes for special ebusd handling
-also edited ebusd (http://sourceforge.net/p/openautomation/code/HEAD/tree/tools/ebusd/) for better handling of bool-items
-time.sleep(1) is for preventing read/write errors (more or less redundant in cause of ebusd-error-handling)
