Error Message Enhancements

[braydonf]

Error messages are repetitive, too long, and the main message of the error is half the way into the string.

var a = new Address();
// bitcore.Error.InvalidArgument: Invalid Argument: TypeError: First argument is required, please include address data.

These could be readable, examples:

// Bitcore Error: Invalid Argument: First argument is required, please include address data.

// TypeError: First argument is required, please include address data.

// First argument is required, please include address data.

Also, it may be helpful to add a link in the error message, such as: http://bitcore.io/api/address.html

I like the option 2. I really like the idea of adding the documentations link on the error.
