Title: Make content_text and ticker parameters optional

I had some trouble figuring out why notifications were not showing in the status bar. Turns out I wasn't setting a ticker, which caused a JSON exception. I made a modification to make ticker and content text optional.
If you accept, I'll be happy to also update the development guide accordingly.
Many thanks!
