Enabling colors on dumb terminal causes error

[bdw429s]

I'm using the java property org.jline.terminal.jna=false to force a dumb terminal while doing some testing on Windows. I tried to get colors back by adding org.jline.terminal.dumb.color=true. While this succeeds in getting me 8 colors it generates an error in the console while JLine starts up. The message is a "warning" level message, but I don't have any logging enabled for JLine.

There's a missing dumb-color.caps here: https://github.com/jline/jline3/tree/master/terminal/src/main/resources/org/jline/utils

It should contain something like the following (untested):

#      Reconstructed via infocmp from file: /usr/share/terminfo/64/dumb
dumb|80-column dumb tty with 256 colors,
        am,
        colors#256, cols#80, 
        bel=^G, cr=^M, cud1=^J, ind=^J,

@gnodet Thanks for the reply. I can try sending this as a pull, but I'm not sure how to fully test it to see if it works.
