update portfinder version to fix auto increment port

[w3cj]

Old version of portfinder is broken and does not find an open port.

Fixes issue: #215

"portfinder": "~1.0.2"

What about using a caret (^) range.

[w3cj]

Currently the exact version (0.4.0) of portfinder is set in the package.json and portfinder recently went from 0.4.0 to 1.x

I'm for ~ range to at least get patches, but avoid any compatibility issues with minor versions.

I'd assume that portfinder adheres to semver and therefore usually doesn't have compatibility problems with minor bumps. The value of semver stands or falls by it's adoption.

I agree with @derhuerst on this. Use and adopt semver but do some sort of QA.

Personally, I prefer 1.x over ^1.0.2 but these are equivalent.

989fa1c sets the portfinder dependency to ^1.0.13--which I hope does the trick for everyone! If now, PRs welcome. 😄
