change property name streetnumber or improve explanation

[myradon]

Hi,

Nice work. I always forget when they collect different types of waste. Now I get notifications. But can you please change docs or property streetnumber. It's (House) number not streetnumber. In Netherlands probably 98% of all streets don't have a number. I couldn't figure out why this plugin didn't work And why property Streetnumber is required. So I gave it a go by filing out my house number. Voila it works!

You have a point. Will take it into consideration.
