Bug fixes

2 little Bugfixes:

* **Event Progress:** 
  The Progress wasn't transmitted correctly in the Events because __progress was supposed to refer to 
   currentData["progress"]["progress"] instead of currentData["progress"]["completion"]

* **Autodetect Baudrate:**
  Timeout was to short so atleast for me OctoPrint wasn't able to connect to my Printer. 
  Changed the Constant 0.1 to read the settings value for timeout
