cr crashes as package version gets accidentially encoded

[michas2]

Packet versions follow semantic versioning, which allows adding build metadata to have versions like this: 3.11627+2e5eff15bf01

cr uses the name and the version to create files like this: cloudbees-core-3.11627+2e5eff15bf01.tgz

Then, in releaser.go it calls downloadURL.String() which will give the encoded representation like this: cloudbees-core-3.11627%2B2e5eff15bf01.tgz

Therefore the file will not be found and cr crashes.

Please stick with the unencoded filename there to avoid this.
