Massive cursor rework... 

Baiscally, fix all the cursor things.  I'm frankly amazed this ever worked.
While we're changing everything, remove pointless arguments from some functions.
Some were ignored, and some only had one possible value.

* So, here's the deal with the cursor...
*
* 1) It's located at vstat.curs_col/vstat.curs_row.
* 2) The size is defined by vstat.curs_start and vstat.curs_end...
* the are both rows from the top of the cell.
* If vstat.curs_start > vstat.curs_end, the cursor is not shown.
* 3) If vstat.curs_visible is false, the cursor is not shown.
* 4) If vstat.curs_blink is false, the cursor does not blink.
* 5) When blinking, the cursor is shown when vstat.blink is true.
* 6) The *ONLY* thing that should be changing vstat.curs_col or
* vstat.curs_row is bitmap_gotoxy().
* 7) bitmap_gotoxy() only moves the cursor if hold_update is true.
* 8) bitmap_draw_cursor() is the only thing that draws the cursor.
* 9) To erase a cursor, you redraw the cell it's in using
* bitmap_draw_one_char().
* 10) The blinker thread via update_rect() will redraw the cursor.
