Removed the donations section.

I gave this some thought and I've removed it for two reasons:

1. My Dogecoin Wallet takes *forever* to sync with the network (13 weeks
   behind) so I uninstalled it. I can't be bothered waiting forever for a
   gimmick.

2. I don't like asking for donations/money. I'd much rather have people send me
   an Email thanking me for my work than for them to donate money. The latter
   means much more to me.
