Gets the character value (as an int) of a cell in the board;

As blocks take up two curses-coordinate spaces,
a cell is defined as such, and its identifying
symbol will be in the righthand space;
In theory, the cell will either be empty (". "),
have an old block (two ACS_BLOCK chars),
or have an active block (two ACS_CKBOARD chars)
