--set option not parsing as boolean

[michelleN]

Original issue is on the kubernetes/charts repo: helm/charts#138

The output of the manifest and computed values is correct, however, a conditional in the template to create a PVC is not being parsed correctly because it creates the PVC even if I set the value of persistence.enabled to false on the command line using the --set flag.

$ helm version

I suggest going through options passed through set with the strconv package (ignoring any errors and falling back to a string). The question is, should we just try to parse booleans or integers also? Order also becomes important, because 1 and 0 can be parsed as booleans.
