Clear Tumblr Tags textbox when new image loaded. Also like changed the version number in the title bar because I guess that's the downside of putting the version number in the title bar.
Actually did the change that I described last commit. Because I'm retarded and described what I was about to do instead of what I just did. Fuck me. Like really, if you're free, I need some more self confidence.
Fixed issue with backspace not working at beginning of lines in the tumblr tags textbox
Fixed tumblr tags textbox not being able to be ctrl a'd
