Revert "Switch back to ERROR, otherwise how to know?"

This reverts commit 15892fbd9f93e4e30a337ad9e44db48fe93aa799.
Refactoring & tidying of much of the serial por

 * If port not found, switching back to error.
   Since the change was made so long ago I am hoping we can go
   back to having this useful descriptive error.  It's really
   nice to be reminded when the port setting may have remained
   from a previous project/setup.

 * Also refactor and extract methods in the ArduinoSerial class for
   clarity.

 * Also renamed variables and method names to be consistent with
   Java standards.
Add A.UPLOAD.FORCE_NO_WAIT_FOR_UPLOAD_PORT var

 - setting this to true allows fully skipping waiting for 
   comm ports to disappear/appear and thus save a few seconds.
