Empty sections in YAML config cause NullPointerExceptions

[fxkr]

Valid YAML file:

mixer:

hardware:
    device: "/dev/ttyUSB0"

Code to load it:

Configuration.load("config.yaml", YAMLFormat)

Traceback:

I have some time left to improve Configrity. Sorry for the long delay. I will try to fix this bug very soon.

Bug is fixed in last commit. In YAML parsing, any key with an empty value will be ignored.
