Here's a few last minute changes:

- (Okay, this first one is a last minute bug).  MDE seems to act funny
running in a DOS shell under Windows.  The problem occurs when you press the
RIGHT mouse button on a vertex.  There is absolutely no code in my C++ source
files for this situation, but it seems to "hang" the mouse.  The escape key
still exits (meaning MDE is still running), but the mouse won't move!  It must
be something to do with the Windows environment.  I'll look into it....

- I got the new DOOM specs (1.1) one day before releasing this version (.90b).
The names I gave to fields 3 and 4 of the linedef structure are  "Control"
and "Flags" (I don't know where those names came from).  The new DOOM specs
have named them "Attributes" and "Types".  The next version of MDE will use
the new names to help establish a standard for the DOOM wad file.

- One change I'll add to the next release is a hot key feature when
changing an object.  Matt Tagliaferri (hope I got your name right Matt!)
suggested hitting a key (like 'R') and pulling up the Rocket Launcher. I
have implemented this, but haven't tested it enough to put in this release.
I promise it will be in the next release.

- WALLS.EXE crashed on me last night. I could not reproduce this crash. I
rebooted and re-ran it and it worked fine.  I tested both the shareware
version and registered version of DOOM and I can't reproduce the crash.
I plan on adding the wall preview to MDE so I apologize if WALLS crashes
on you.  It should be fixed in the next release (added to MDE).

- Also re: WALLS - I'm not positive that the wall textures are being
displayed *exactly* right.  For the majority of the walls they look fine,
but some just look "out of place" and it makes me wonder if my code or
possibly the WAD specs are not correct.  I'm looking into this.
