Batch is clueless about double quotes

This is especially important for setting the paths - you don't want to set a 
path with quotes around them because it just then reads it as a single string 
variable, path -> boom.

However, we may probably need to revisit this issue to handle individual 
variables that are going into the paths at some point in time (they need
quotes).
