Removed currentLocale.setLocale from ScopedUI.init - it confuses the Locale setting model
Exception thrown if defaultLocale is not in supportLocales
Explicit dependency on Vaadin Testbench added to testapp gradle build
Removed spurious locale=defaultLocale.  Expanded javadoc
See #273 Re-implemented existing Translate functionality but with chaining enabled, and static translation maps defined through a PatternSource implementation
Fix tests for non-UK platform
Fixing test failures on non-UK platform
LocaleContainer (and therefore DefaultLocaleSelector) list languages in their own locale.  Germany is therefore always Deutsch (Deutschland) regardless of the display locale of the rest of the page
All tests green on both UK and non-UK platform (see #272)
Explicit test still required for #271
Merge remote-tracking branch 'upstream/develop' into develop
