* First pass at moving to SDK EInkDisplay library * Add 2-bit grayscale text and anti-aliased rendering of text * Render status bar for empty chapters * Refresh screen every 15 pages to avoid ghosting * Simplify boot and sleep screens * Give FileSelectionScreen task more stack memory * Move text around slightly on Boot and Sleep screens * Re-use existing buffer and write to whole screen for 'partial update'
