Key bindings for more convenient interface

[elexunix]

Hello! The database is great! I wonder if it is possible to make, say, the space key be used to automatically play the best move out of the list. I guess it is relatively easy, since it just requires adding a few lines to the front-end. This will make it even more pleasuring to use, since it is an often usecase -- to look through the optimal play line, currently it requires clicking on a move each time

Good idea. Added the space shortcut.
