Added

Translation into Simplified Chinese. (Thanks to @2013ZRZ, it's the first community translation of Gauguin!)
Switch to compact key pad buttons and alter the layout automatically if a grid with size greater
than 9 gets played and the display dimensions are phone wise limited. (Thanks to @mccartney for the idea!)
New option the allow grids with size greater than 9 to obtain most of the screen, which means
getting a rectangular (that is a non-square) grid layout. This may look a bit less elegant than
the usual one, but features more space to display readable pencil marks and so on. (Thanks to @mccartney for the idea!)

Fixed

The info box shown when finishing a game gets no longer squeezed if there is not enough space left
for it. Instead of, the box may overlap the grid.
This is not pretty, but a kind of workaround especially when using a rectangular grid shape,
minimizing the space left to be used by e.g. this info box.
