Add params as to function Fix #6

[leocaseiro]

Fix issue #6 adding params as array.

Needs to pass as array while the function must be the first parameter.

Usage:

<div w-mousetrap="{ a: [someFunc, scopeVariable, 'string variable'] }">

$scope.someFunc = function(event, params) {
    event.preventDefault();
    console.log("Super cool", params);
};
