Adjust Grid subsystem

Browse Source 
Rename ROWS to LINES (it's what VE uses). Also, don't use COLS and
LINES as immediates in the Grid subsystem: we expect those words to
be available at runtime.

allows random access to it.
COLS -- n Number of columns in the device
ROWS -- n Number of rows in the device
LINES -- n Number of lines in the device
CELL! g pos -- Set glyph at pos
"pos" is a simple number (y * cols) + x. For example, if we
have 40 columns per row, the position (x, y) (12, 10) is 412.
have 40 columns per line, the position (x, y) (12, 10) is 412.
A glyph is ASCII-0x20. If the resulting glyph number exceeds the
number of glyphs in the font, it's up to CELL! to ignore it.
