Updated release date for v0.7.0

Hey guys,

I'm afraid I have to postpone the release of v0.7.0 for a couple of days.
There are still some bugs that need fixing and not all of the renders are finished.

I have been having hardware issues that have slowed me down a bit for some weeks now.
I bought a new render system that should arrive in a week or so.
Hopefully that will speed up productivity for the coming months and give me the time to reinstall my current one.

TLDR: The release will be on Sunday.
Sorry about the delay!
