WIP multi bit width templated 1d bitblit

pointer arithmetic for bitblit 1D

copied over bitmap operations from libEmbedded

changed vcom handling a bit

added vcom control in memory lcd

split memlcd driver into driver and display middleware

LPC84X spi write

updated driver and added display middleware

added methods for scrolling and block pointer, renamed some constants

switched to page addressing mode so you can change the pointer
