Because both proc.on.close and stdin.on.end were called for each process
the return callback was fired twice.

Move all the parsing code to proc.on.close - so it works as desired.

removed restiction to install node-winreg on windows platforms only

node-winreg can be installed on any os now
this enables node-winreg to be used in npm post-install scripts
execution of node-winreg in non-windows environments will simply fail
modified the output of 'npm test' so it becomes more readable
bump version
