Subject: [PATCH] [Dropdown] Allow ignoring of case when getting an item

Currently get.item compares labels and values case sensitively. This can cause duplicates when `allowAdditions` is `true`. To prevent these duplicates get.item should be capable of comparing labels and values while ignoring case.

However the current behaviour should be preserved by default.

To achieve this a new setting is added called `ignoresCase`, which when `true` will disregard the casing of labels and string values when performing the comparision.
