• better x-axes in plot.cvrisk and possibility to change xlab
• parallel cvrisk on Unix systems only (multicore isn't safe on windows)
• included new penalty for ordinal predictors (in bols())
• corrected bug in bspatial (centering was not used for Xna)
• removed output of dfbase (which is seldom used) in gamboost
• changed manual for coef.gamboost
• make sure NAs are handled correctly when center = TRUE in glmboost
