Added a setting to disable cursor movement after displaying characters.

If the setting LCD_isCursorMoving is set to FALSE, the cursor won't move after displaying characters, strings or numbers. If set to TRUE, cursor moves normally as before. Default value is FALSE. This makes e.g. displaying numbers on one position (like stopwatch) easier since cursor stays there. To move cursor while LCD_isCursorMoving = FALSE, use either LCD_setCursor(x,y) or move functions like LCD_moveLeft(n).
