1. (Windows) Further refinement to note #3 on edit 727 (below); it now looks at the background color in the first position of all 24 rows and chooses the color that appears most frequently (i.e. the "mode" in statistical terms) for the border/margin color.
2. The STR(x) function now matches the AMOS version precisely by dropping the leading zero in values between -1 and 1. (That is, it now returns ".123" and "-.123" instead of "0.123" and "-0.123".)
3. (Windows) Fix handling of data output to pseudo-aux port using TAB(-1,82). Previously, this data was appearing on the screen and in the screen map. Now it is thrown away, except in the case of the telnet server mode, in which case it is passed through to the telnet client but does not appear in the screen map. Note that this form of aux printing was not implemented in A-Shell/Windows because it is just as easy for all apps that we know of to print the "normal" way in a Windows environment.
4. MSBOXX.SBR now supports a new BOXCOD flag, 262144 (BOX'SRF), which has the effect of putting "serifs" on the ends of the lines that appear when the box is actually just one line (because the top and bottom, or left and right sides are the same.)
XCALL DRAWBX,SROW,SCOL,EROW,ECOL added which uses this feature. Note that unlike MSBOXX, which draws the box AROUND the specified coordinates, DRAWBX draws them ON the specified coordinates.
5. Support ^T and ^R as alternatives to PgDn and PgUp in XYESNO & XENTER.
