Title: Fix nil error when used together with kicker

When using spin together with kicker as advertised in the README, the following error may happen:

```
spin:237:in `initialize': can't convert nil into String (TypeError)
```

This change fixes an in-place `map!` operation so that the subsequent `compact` and `uniq` actually have an effect. This strips `nil` arguments that are the result of passing empty strings to `spin` on the command line.
