Padding fixes

[martonmiklos]

I have uniformized the InfoLabels: no space is necessary to add to the label. (Removed the spaces from all translations with this script: https://gist.github.com/martonmiklos/21764ffd726721abd6ace295bd816f1f)

• Adjusted some paddings in the about dialog: the authors are now padded a bit.
• The Detailed view items are padded a bit from left
• The map and diagrams page left column InfoLabels are padded a bit
