concrete fonts

[Eckhart Guth�hrlein]

I tried to use computer concrete fonts via

\setupbodyfont[con]

As far as I have understood the font selection in context, this should 
work. But it doesn't, because a font 'saccr10' is required, which is not 
available (and does not exist, to my knowledge). Maybe this is a bug in the 
typescript files, since it should be ccr10?

\definetypeface[con][rm][serif][concrete][default]
\setupbodyfont[con]

works and gives me ccr as the default font.
