Minor: Icons and text aligned on top rather than center

[hardcodet]

Minor issue: If you have icons and text of the same size, they don't align nicely in the center but on the top. I ended up applying a little hack with a centering view:

const icon = (name: string) => <View style={{flex: 1, justifyContent: "center"}}><FAIcon name={name} size={16} /></View>

Sorry for the delay.. I think this might be because of https://github.com/expo/react-native-action-sheet/blob/master/src/ActionSheet/ActionGroup.tsx#L158. I can check if changing the value to center breaks the UI at all.

This was fixed in #188.
