Don't merge (yet): Delete unused assets, second try

[abrock]

Running a linkchecker on the first try #366 revealed that I deleted two assets which were actually used.

[abrock]

This version seems to have no missing assets (checked using "linkchecker" from Debian testing on the preview build). So the question is:

1. Merge it to clean up the build / deployment but keep the files in the history, or
2. Rewrite the history to actually reduce the repo size?

[tabascoeye]

Reduce build time and deployment size would already be nice.
I'm not sure of the implications of rewriting git history.
Maybe others can comment?

@elsbrock @lutoma ?

[elsbrock]

Should be perfectly fine, but every fork/clone will potentially become invalid.

[tabascoeye]

@abrock then let's rewrite history 🖖

[abrock]

Yes, but let's either merge or close all other open pull requests first.

[tabascoeye]

all other pull requests closed/merged.

==> rebase or merge master back into this and go on with re-write, please @abrock
