Initial release: everything is almost working

Why is it an alpha-release?

Most of the features that are present in any way are working. All essential features seem to be working as well.

Not yet done in this release

Border patterns broke, SVG pattern connection is present as a button but isn't implemented. After completing these features or removing them (first option is obviously the preferred one), the version will be considered a full release.

Contributions are very welcome :)
