Finished a majority of the beta functionality

The following options are now available:

• primary and secondary theme colors. Paid??

• logo upload

• several font options. You can choose separate fonts for your blog's title, subtitle, and body

• define seo title, description and, if needed, a canonical url - for each article

• support for multiple blogs. You choose a different branch for each one. May be a paid feature.

Things still in the works:

• custom domains. May be a paid feature.

• plausible analytics

• article header pic
