* The intent of having the length variable was to avoid sending trailing
whitespace for each line, but the previous code never read the variable.
Instead, every line it sent was the width of the terminal window.
* There was a bug where running console.exe inside a TERM=cygwin terminal
resulted in excessive line feeds. This change mitigates that bug, but
doesn't fix it. The problem is that the agent assumes that after it
writes to the last column of a line, the cursor is still on the same
line, but this isn't true for the TERM=cygwin terminal.
* Add a note on how to use instsrv and srvany.
* First look for Agent.exe in the same directory as TestNetServer.exe
before looking for the executable in the build directory that Qt
Creator uses.
* Write a script that copies MinGW/Qt DLLs to a single directory.
