Separating Key and Value in Dropdown shared component

[alexjoybc]

react-shared-components/src/components/dropdown/Dropdown.js

Lines 26 to 28 in 3a3312d

	<option key={val} value={val}>
	{val}
	</option>

For better usage of the dropdown it would be nice to be able to pass an array of key value pair so that the displayed text will be the value and the key would be used as the key
