Stop the flickering vertical stripes on the CYD panel (0.2.49)

Browse Source 
The cheap ILI9341 panel showed a fine vertical line pattern that shimmered
when you moved your eyes or the board. Frame inversion (0xB4 0x07) at the
panel's highest frame rate (0xB1 0x00 0x10) removes it; VCOM stays default.
Firmware 0.2.42 for both boards, version only on the Guition.
