BUGFIX: Column spacing and missing bold font

[crydotsnake]

This pull request provides a few bugfixes for the Neos website. Previously it was not possible to mark text as Bold in the word processor, because the required font file was not loaded. I went through the layout afterwards, and everywhere where the text was Bold afterwards (like in the navigation) I set the font-weight to regular, so the layout wouldn't break. Also, in the text with image element, there was no space between the image and the text when I placed the image either on the left, or right side. I also added a small space between the text and the icon in the ImageTeaser, so that it doesn't look so squeezed on top of each other. But I have summarized my changes in screenshots.

Thx! Looks good by reading but will test it locally.

I updated the title as its more like a bugfix and should be more precise.

Yes, in hindsight you are right.

I updated also the description above

This is not necessary. We need to adjust the base mixin h() to use $regular. Additionally you can remove the font-weight overrides in the mixins h5 and h6 as they would break the current website styling.

You can check the impact of this change e.g. on the schedule page of the NEOSCON.

@crydotsnake did you implement all requested changes by @ahaeslich

[crydotsnake]

Sadly not. Unfortunately I have totally lost sight of that

[ahaeslich]

@Sebobo is this MR still relevant regarding that you are working on the website right now?

@ahaeslich it will have some conflicts as I resolved the font problem with a variable font type, but I didn't touch the spacing part.

So rebasing and targeting the development branch would be best.
