IllegalArgumentException when color.layer contains "{ }"

[chihchun]

When having this config in preferences.xml, it caused josm throws IllegalArgumentException
<tag key='color.layer {5DE308C0-916F-4B5A-B3DB-D45E17F30172}.gpx' value='#FF0000'/>

Because org.openstreetmap.josm.data.Preferences.getColorName(Preferences.java:746) just passed the layer name as key to org.openstreetmap.josm.tools.I18n.tr(I18n.java:157).

The braces need to be escaped.
