375/space grid

[pyphilia]

Space Grid is improved so it:

• evenly distributed when more than one space is on one row depending on the computer screen
• does not show strange spaces between rows
• does not take the full screen if there is only one space on one row (there is some maximum width set)

A maybe strange behavior would be that depending on the card size (which depends whether there is a description or not, the image size perhaps) the cards might not be aligned vertically, but they still are evenly distributed horizontally.

Forcing the vertical alignment (set xs=4) would create margin on the right depending on the screen size.
