Print version on new line

[laynemcnish]

When running packr version, it should print the version on it's own line.

Current behavior:

$ packr version
v2.5.3$

New behavior:

$ packr version
v2.5.3
$

When checking the recommended behavior against Cobra, their example uses Println, as well.

var versionCmd = &cobra.Command{
  Use:   "version",
  Short: "Print the version number of Hugo",
  Long:  `All software has versions. This is Hugo's`,
  Run: func(cmd *cobra.Command, args []string) {
    fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
  },
}
