Support SublimeLinter

[egeerardyn]

It would be very nice if our color schemes could natively support SublimeLinter.

I had a quick look at one of the automatically converted schemes. At the end, it seems that the following fragment is added:

    <dict>
            <key>name</key>
            <string>SublimeLinter Warning</string>
            <key>scope</key>
            <string>sublimelinter.mark.warning</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#DDB700</string>
            </dict>
        </dict><dict>
            <key>name</key>
            <string>SublimeLinter Gutter Mark</string>
            <key>scope</key>
            <string>sublimelinter.gutter-mark</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#FFFFFF</string>
            </dict>
        </dict><dict>
            <key>name</key>
            <string>SublimeLinter Error</string>
            <key>scope</key>
            <string>sublimelinter.mark.error</string>
            <key>settings</key>
            <dict>
                <key>foreground</key>
                <string>#D02000</string>
            </dict>
        </dict>

Probably the colors could do with a bit of tuning to match our colors.

Apparently, we do already have support for this in our main theme, but not yet in the secondary ones (Markdown, Monokai, Twilight, ...).
