Add the ability to call CBWIRE UDFs from the cbwire template as computed properties are too limiting.

[grantcopley]

Currently you call computed property functions from your wire template, but they are very limiting.

1. You can't pass arguments
2. You must always return a value
3. The computed property cannot easily parse other computed properties it may need.

I've never liked the computed properties implementation to be honest.

What if we could just call any methods defined within our wires?

data = {};

function add3( num ) {
    return num + 3;
}

....

<cfoutput><div>#add3( 10 )#</div></cfoutput>

Being able to call UDFs directly from the template would add a lot more flexibility over computed properties.
