Issue with mulirow tooltip translation strings

[krzychu124]

I've noticed an issue while working with #572.

If translator add invisible line break instead of \n Crowdin generates multiple rows for singe translation string.The rest of translation after line break is not properly loaded in-game.

I suggest split multirow tooltips and separate key modifier (combination Ctrl/Shift/Alt with click) translation from tooltip text because it confuses translators.

I suggest the plan

1. Check if that is valid CSV (quick google search says that yes, it is)
2. If that is, fix CSV loading code to consume newline if a quotation mark is open.
