Add newlines so the file description formats aren't messed up

[prototyperspective]

Please add line breaks where there are line breaks in the video description because on for example Youtube these are formatted as newlines while two line breaks are needed on WMC to cause a newline. One can manually fix this by appending <br/> to every line break.

It only makes sense to not apply the same newline-formatting for specific types/parts of descriptions such as tags where it's useful to have the description more condensed. Alternatively, one could have a checkbox for "apply same text formatting" (which adds these newlines) vs the more condense formatting without newlines for single linebreaks.
