updated to v0.2.5

Update to v0.2.5: quality of life update:

General changes:

-You can now navigate between menus using your keyboard arrows, return/spacebar keys and the escape button. holding escape while in game will also make you go back to the main menu without having to use your mouse.

-fixed a bug where the warning used by the pc algorithm to tell if it is using a piece out of vision would not work properly.

Browser changes:

-in an attempt to bridge the gap between the browser version and the desktop version, browser is now able to use the pcvision though, since browser does not have threading, the pcvision can only see 6 pieces in advance instead of 7 (or else, the lag would be too noticeable).
