nodeProcessCommandLine should be allowed to be a relative path

[MrHacky]

This greatly simplifies deployment for us on our test servers, where a simple unzip of our release package is the only step needed.

See #356 for an implementation. (though that only works if the path starts with '.' as i didn't see an easy way to check if a path is relative...)

We are not going to support this due to security reasons.

[MrHacky]

Okay... could you please explain what those reasons are?

[RamIdeas]

Security reasons? Surely being able to specify any .exe anywhere on the file system is more of a security concern

Would like some clarification on this as well?
Where's the problem allowing a path relative to the current directory only like bin\node.exe?
This would work then on different machines as well.
