Modernize Function like we've done for Modify, possibly deprecate load/refresh

[brandonscript]

{
    "_type": "Function",
    "do": {
        "myActionSheet": "present"
    }
    "on": "touchUp"
}

Would give some serious thought to getting rid of Load/Refresh entirely and making them globally available functions:

{
    "_type": "Function",
    "do": {
        "myDataSource": "load",
        "myTable": "refresh"
    }
    "on": "touchUp"
}
