There is a misspelled translation template operator in design/admin2/templates/ajaxuploader/upload.tpl.

The "Step 1/3: Upload a file" header is currently untranslatable and generates the following warning:
eZTemplate @ design/admin2/templates/ajaxuploader/upload.tpl:4[16]: Operator 'i18' is not registered

The call to the translation template operator has been written as "i18" rather than "i18n".

Steps to reproduce

1. Edit or create a node with an attribute that shows the ajax uploader (such as an objectrelation).
2. Click "Upload a file".
