rstimecourse2: added PCA algorithm
rstimecourse2: PCA shows more output in verbose mode, small bugfixes
rsregression2: fixed bug in parsing the regressor file
rstimecourse2: converting to standard scores prior to running PCA, fixed number of components can be specified
rstimecourse2: minor help fix
rstimecourse2: added tPCA
rstimecourse2: spatial maps can now be saved for spatial and temporal PCA
