configure debugger main window width

[garfieldnate]

Request from Bob W:

When we are sourcing files, we end up with some gps that add ~1000ish productions and that makes the debugger window as wide in characters as the number of productions that were added. Id like to limit how far the window can expand.

This is caused by Soar printing an * for each production sourced, so in this case it prints *****************************....., (a thousand asterisks).

More details:

This is annoying because the user only cares about the ~100ish columns, which is where most of the output lives. With the window becoming very wide, the control on the scrollbar becomes tiny, and moving it a little bit will scroll way past the end of column 100. Bob shared this example:

Bob suggests:

It might be simplest to insert a line break at the column configured by the user. We could print a ⏎ at the end of the line that got split to indicate that it was split.

Might be clearer to insert the line break and then put the the character that signals continuation to the user at the beginning of the next line instead of the end of the previous one.
