Changes
- If loading of an item fails HABApp doesn't skip loading of all items any more
- Added Loghandler: ``HABApp.core.lib.handler.MidnightRotatingFileHandler``:
A file handler that waits until the file has a certain size and then rotates at midnight.
This is the default when the logging.yml gets created
Made this the default file handler for logging.
- Removed timeout for connection to openhab
- Added example how to check Thing status
