Runtime error when autoFocus applied to FormInput element

[acampbellb]

There is an error in the source code for the FormInput component. The functions 'focus' and 'select' both reference a member that is 'undefined' (input). The following code changes resolve the issue.

file: components\FormInput.js
function: focus
old:
focus () {
this.input.focus();
},
new:
focus () {
this.target.focus();
},
function: select
old:
select () {
this.input.select();
},
new:
select () {
this.target.select();
},
