Updated mediawiki/extensions
Project: mediawiki/extensions/UploadWizard  8ce50fe942f24a6a1d77653b38f53a19c01480d9

Move showTooManyFilesWarning to the wizard object

This was stupid and it made refactoring the upload stuff very difficult

Also moved the handler construction out of the Upload constructor, because
we don't need it until later.

Bonus: Tore out uploadToAdd, which is stupid anyway.
