commit b88383e838aa4ca1435b5b96d164642b2db53746

Support multi-line braille in the virtual braille display.

The virtual braille display now can display multiple lines of braille and text. One can now change the number of rows and columns of the display in the options page. They can also change the display style, whether it is interleaved or side by side. Interleaved is when there are alternating lines of braille cells and regular text characters. Side by side is when all lines of text are on the left and all lines of braille are on the right. When one hovers their mouse over a [braille/text] cell, the corresponding [text/braille] cell would highlight.
