com.unity.localization@0.3.1-preview

## [0.3.1] - 2019-05-02
- Added KeyDatabase. All string keys are now contained within this and mapped to a unique(to the database) id value which is used by the table.
- Assets are now grouped in Addressables by the locale. This allows you to serve them on-demand for a particular language, instead of bundling them with the game release. Shared assets are stored in a separate group.
- Assets are now removed from Addressables when they are not referenced by any Asset Tables.
- Fixed UIElements issues in 2019.1+.
- Merged LocalizationPlayerSettings into LocalizationEditorSettings.
- Removed AddressableAssetTableT.GetAsset. GetAssetAsync should be used instead.
- Added option in `Asset Tables Windows` to add a missing table if a table does not exist for all available Locales.
- Updated to support Addressables version '0.6.8-preview'.
- Fixed UIElements compilation issues in 2019.1+
- Updated to Addressables version '0.7.5-preview'.
- Removed support for .Net 3.5, this is due to a limitation in Addressables.
