Add Donate on Webpage and in App

[garrattg]

I want to donate money for all your hard work. I personally like paid apps because I know they are more likely to be supportive. This app has been a game changer to my work flow, and I know it has such amazing future potential. I have also realized that unlike other apps that can be easily copied, this on in particular is very tricky because its nuanced in interacting with operating system.

Adding a button for people to donate would be cool. I think i've seen "buy me a coffee" in other apps.
