[IMP] pos_restaurant: make floor editing more touchscreen friendly

Before this the table edit handles where quite small. This was no
problem when editing a floor layout with a mouse or perhaps with a
stylus on a touchscreen. It was however very difficult to do with your
finger on a touchscreen.

This increases the size of the handles by a factor of 3. To make room
for this the 4 handles on the sides (non-corner ones) have been removed
on square tables since you can technically do any operation you want
with just the corner handles. The only functionality we lose is resizing
a table while constraining it's width/height, but if such fine grained
control is needed then the tables can still be edited in the backend.
