Support arguments to scripts

[PEZ]

Today the keyboard shortcuts are bound to script files. What if they could also be bound to a function in the script file and to specific arguments for those functions?

Something like so:

    {
        "key": "cmd+alt+i",
        "command": "joyride.runWorkspaceScript",
        "args": {
            "script": "ignore_form.cljs",
            "fn": "ignore-current",
            "fn-args": [
                {
                    "levels": 2
                }
            ]
        }
    },
    {
        "key": "cmd+alt+t",
        "command": "joyride.runWorkspaceScript",
        "args": {
            "script": "ignore-toplevel.cljs",
            "fn": "ignore",
            "fn-args": [
            ]
        }
    },
