Splitting main webpage and gallery

[mberz]

Building the main webpage and gallery currently are happening from this same repo.
This may lead to a deadlock in updating the webpage if parts of the gallery causes issues (most likely due to version number conflicts, deprecations, etc.)
For this reason I propose to split the primary webpage and gallery and create a separate repository for the webpage only.

this would just shift the Examples tab into a separate repo, wouldn't it?

Yes, or more precisely, it would shift ever except the examples tab into a separate repository.
At least if we want to keep the naming consistent.
