Removes all empty ones
Removes some redundant/duplicates ones (please committers don't commit those again, I know it's not easy to catch, hopefully now we should have less of them)
Automatically replaces some tabs
Few French labels improvements
Removes 2 orphan entries ("ja" & "cs")
Fixes the schema header of WebtoolsUiLabels.xml
