Please make the following changes to the configuration for Wikimedia Incubator. I know, each request should be in a separate bug but these are all very small changes, so I don't really see the need to make several bug reports. One bug makes it easier.
Local consensus is http://incubator.wikimedia.org/wiki/Incubator:Community_Portal#Configuration_updates
- Change wgUploadNavigationUrl from '/wiki/Incubator:Upload' to '/wiki/Special:MyLanguage/Incubator:Upload'
- Set wgUploadMissingFileUrl to '//commons.wikimedia.org/wiki/Special:Upload'
- Remove namespace Lost, Lost_talk (they are no longer needed and are empty)
- Set wmgBabelUseUserLanguage to true
- Add 'translationadmin' to wgRemoveGroups for bureaucrats
