Add different view modes

[BaldissaraMatheus]

Added different view modes that change how much screen space cards. The modes are:

• Regular: Easy to read and manipulate, has fixed minimum height;
• Extended: Like regular, but also displays some of its content;
• Compact: Like regular, but has no minimum height;
• Tight: Heights and gaps are reduced, card name and tags takes both a single row.
