Title: Add option to set the :remainder_mark.

Added an option to set the :remainder_mark (along the lines of :progress_mark) that allows the user to set the character used to represent the remaining progress to be made along the bar. Some pretty cool effects can be achieved by using Unicode characters for the two marks, e.g. a small dot for the remainder and a big block for the progress mark.
