Updated local screenshot testing configurations. (#11814)
* A separate screenshot module hasn't been in use for a while but local
testing configurations and instructions weren't updated to the new model
at the time. Could use some further cleanup but this covers the basics.
* Some tweaks to ScreenshotBrowser to get it functional again, although
the actions for automatically replacing or adding alternative
screenshots still require work and have thus been disabled.
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.

Makes it possible to run DSL in the uitest project using the same
configuration as before.
Note that this change might not fix all issues with DSL.
