Added jQuery File Upload plugin (messy implementation)
jQuery File Upload improvements (basic implementation, no custom styles, no backend implementation)
Basic gulp setup (check wiki for node/npm/gulp install instructions)
Frontend customizations for the file upload plugin
References to files are now kept from one request to another (i.e., donate -> summary)
Finished a basic version of the file upload logic, left to do: remove file references when a user removes a file
Files can now also be removed by the user
