  1. xss: XSS To LFI Vulnerability

    This addresses a vulnerability found by [AkkuS CW](https://pentest.com.tr)
    where a simple XSS attempt can lead to an LFI (Local File Inclusion) attack.
    The issue stems from the system returning the unformatted file contents in
    an error message when uploading a CSV to the User Importer. This formats the
    contents before uploading so that if the contents are returned in an error
    message they will not be executed by the browser which therefore prevents
    XSS attempts and the possibility of an LFI attack. This also formats all the
    user-created data sent to ImportError to prevent the same issue.
