Stefano Ceccherini 65e63b987d PaletteConverter now exports a static InitializeDefault() method, which
can be used (and is, by _init_interface_kit()) to initialize the ... 
er... default instance of 
PaletteConverter using the system color map, thus avoid building the 
list of colors, which takes some time. Fixes bug #505.
