VHDL snake based on DE2-115 board

implement steps

display a red point on the screen

let the redpoint move, left, right, down

design standard shape of the block

let the block could be rotated

design the game logicality

others

1. VGA_SYNC_N control if show, N means 0 is activated

view code

VGA_SYNC_N <= '0';  -- display
VGA_BLANK_N <= '1'; -- do not dispaly

2. these assignments could work by now, which just include VGA show info
