ensure that displays are done in current video page.
fixed: switching between hex and binary mode didn't clear the first data
line.
fixed: if HD access had to use int 13h, ah=3 (old write function),
a wrong address (read buffer instead of write buffer) was used.
added SETM43 tool. If it works with the graphics card, WDE's look
might improve since a 8x14 font (instead of 8x8) is used then.
accept 'x:' or 'xH'/'xF' on the command line when WDe is started.
source changed to true tiny model (reduces binary size).
lot of "spaghetti" code cleaned.
find function will move cursor to the start of the found string.
Home/End key in main menu move cursor to start/end of current sector.
"find next" function added. Also, find will now start from cursor
position in current sector, not from the current sector's start.
