Fixed an issue when distributions were not defined for sequential data g...

The function 

createData <- function(paramSet, n, indDist = NULL, sequential = FALSE, facDist = NULL, 
    errorDist = NULL, saveLatentVar = FALSE, indLab = NULL, modelBoot = FALSE, realData = NULL, covData = NULL,
	empirical = FALSE)

used to fail when sequential = TRUE and facDist = NULL. This patch checks if faddist is null and if so, use mvrnorm for data generation. The implementation is identical to what was used already when sequential = FALSE and indDist = NULL

The changes look large because of a line ending issue.
