VIDEO_CURSOR_POSX should be 4-byte aligned

[Ryzee119]

There's instances in the cromwell code base of cursor offsets that are not aligned on 4 byte boundaries.
The font render code does not check for this and results in incorrect bytes being set in the framebuffer. In some cases it could even result in writing to areas outside of the frame buffer.

As a minimum, this function should check VIDEO_CURSOR_POSX is divisible by 4 and fix before passing the framebuffer pointers.

void BootVideoChunkedPrint(const char * szBuffer) {

The most prominent issue of this is the below comparisons in the Text menu titles. The colour should be purple.

Cursor Positions Adjusted correctly:

An example of bad cursor position is here. The above example was created by changing X cursor position to 72.

	VIDEO_CURSOR_POSX=75;
	VIDEO_CURSOR_POSY=125;
