Align footer-links in the center of the page

[nop33]

I noticed that the footer links are clearly not in the center of the page and it seems like it was intended to be. This PR fixes this issue. To demonstrate:

Before

After

Also, is there a reason why the right padding of the footer is 5px but the left is 10px in indico/web/client/styles/partials/_footer.scss?

I'm curious, why do we need to stretch the outer elements for this? Shouldn't space-between on the container already spread them evenly?

[nop33]

If all items have flex-grow set to 1, the remaining space in the container will be distributed equally to all children. In this case we have 3 children and we want the middle one to be at the exact center. So distributing the remaining space to the first and third child, we make sure that the 2nd one will always be in the middle.

Even if the third element has no content ;)

yay, merged!

Hey @nop33, I just noticed that this PR broke the footer logo text on the login page:

I know it's not october anymore, but would you be willing to fix that?

[nop33]

Sure, I can have a look!

rm -rf node_modules is the easiest option; npm doesn't like broken symlinks in there

[nop33]

same result

[ThiefMaster]

try deleting package-lock.json as well

I did it right before I saw your comment. Worked, thx!
