Install instruction might not work if `.Xresources` contains `*customization: -color`

If your `.Xresources` contains line
```
*customization: -color
```

then X11 apps will load their default settings from `/etc/X11/app-defaults/$APP-color` instead of `/etc/X11/app-defaults/$APP`(at least that's where the defaults are on Ubuntu).

On Ubuntu also, `/etc/X11/app-defaults/XTerm-color` contains the following lines:

```
! These are the 8 ANSI colors and their bright equivalents. Depending on
! other resource settings, xterm may use the bright colors when displaying
! bold text (see the boldColors resource).
*VT100*color0: black
*VT100*color1: red3
*VT100*color2: green3
*VT100*color3: yellow3
*VT100*color4: blue2
*VT100*color5: magenta3
*VT100*color6: cyan3
*VT100*color7: gray90
*VT100*color8: gray50
*VT100*color9: red
*VT100*color10: green
*VT100*color11: yellow
*VT100*color12: rgb:5c/5c/ff
*VT100*color13: magenta
*VT100*color14: cyan
*VT100*color15: white
```

Xterm favors these `Xterm.VT100.color[0-9]*` settings over the generic `*.color[0-9]*` settings, so the Dracula settings set in `.Xresources` as per the installation instructions do not work.

Suggestion: also set the `VT100` settings in the `.Xresources` file, like this:

```
! Dracula Xresources palette
! For all apps
*.foreground: #F8F8F2
*.background: #282A36
*.color0: #000000
*.color8: #4D4D4D
