Change Details

When the error reporting JS is called, collect environment information and add it to the error report: - MediaWiki version (maybe extension versions as well) - enabled gadgets and their versions (maybe - should be considered carefully due to privacy implications) - same for user scripts - consider setting up some sort of hook for extensions to add error information (made-up example: for UploadWizard, the developer would want to know whether the user enabled chunked upload or not)
