Publish to Chrome Web Store

[Yutsuten]

Firstly, thank you very much for this awesome extension. Installed it on my Chromium (Debian), and I'm loving it!

To make it more accessible to users, it would be nice to publish it to Chrome Web Store, so anyone can experiment this awesomeness without having to bother with manual installation.

I personally had to spend many hours to find the problem and installing required python packages, until it finally worked. Many other users may quit because of this annoying step.

Thank you!
