allow :focus based verbs to take a pattern

This allows verb definitions such as the following ones:

```Hjson
    {
        invocation: "gos"
        execution: ":focus"
    }
    {
        invocation: "go {path}"
        execution: ":focus {path}"
    }
    {
        invocation: "goroot"
        execution: ":focus /"
    }
    {
        invocation: "gotar {path}"
        execution: ":focus {path}/target"
    }
```
