Add a maven plugin for formatting according to Eclipse settings
Running formatter:format will format all files in a submodule using an
embedded Eclipse compiler (based on Neon SR1)
according to the regular formatting settings file.
Add static helpers for creating callback data providers (#8314)
Cannot overload the same create method for this purpose since it
conflicts with T... overload. Each case is instead given its own
descriptive but still discoverable method name.
LegacyApplication explicitly uses "reindeer" as default theme.
Extended AbstractTestUI to AbstractReindeerTestUI, that all old tests now inherit.
All new tests should be based on AbstractTestUI.
Also added AbstractReindeerTestUIWithLog for those that needed it.
Removed all found @Theme("valo") and used proper parent test class.
