Changes to TT4 for beta 2

[onemaggie]

This PR includes the bugfixes from the GH repo since Beta 1. Mainly we have renamed patterns and images, improved image descriptions, polished a few of the templates to fit better the design and addressed some a11y concerns.

We also changed the required version to 6.4, aligning it with the last few default themes since we are making use of some of the features that will make it to 6.4, such as aspect ratio.
