Remove blanks from the address field

[greasyy]

I made several addresses and copied and pasted them into the address book, but I couldn't send any coins to them because I copied blanks in front of the address too. I had a ton of money sitting in the wallet and was frightened it might be a bug and Sphere showed me an address from which I don't own the private key until I discovered the blanks. Many people are experiencing the same problem and this can easily be resolved by forbidding blanks in the address field.
