recommendation: adding donation link to github readme and to website

[user8446]

I recently donated after looking for the link through your website and the github readme and finally found your paypal link in the about section of the app. May I suggest adding this elsewhere so other donators can easily help with great open source projects such as yours to help with development.

Thank you!

Thanks for your donation and suggestion very much! I will add donation link when I update README.md.
