Change method naming for Likes

[ArkeologeN]

Current Like story syntax is something like:

angel.likes.create({
    likable_type: '',
    likable_id: ''
}, function(err, body) {
    if ( err )
        return console.log(err);

    console.log(body); // Something with messages here.
});

We need to change it as:

angel.likes.like({
    likable_type: '',
    likable_id: ''
}, function(err, body) {
    if ( err )
        return console.log(err);

    console.log(body); // Something with messages here.
});

In the same way, change the Delete / Unlike process as defined:

angel.likes.trash('like_id', function(err, body) {
    if ( err )
        return console.log(err);

    console.log(body); // Something with messages here.
});

TO

angel.likes.unlike('like_id', function(err, body) {
    if ( err )
        return console.log(err);

    console.log(body); // Something with messages here.
});
