fixed a glitch in the prog8/vtui example (#117)

Browse Source 
When the program starts, before the screen is modified, save_rec
is called to capture the cx16 logo.

The fix was to not do the second call to save_rec until after
vtui is used to draw the boxes on the screen.

Before the this fix, the initial replacement issue was of the
logo and not the portion of the screen originally modified by
vtui.
