v1.5.1

• No breaking changes, but a lot of new stuff, improvements and fixes
• New event-driven API (see docs for Constructor and .insert() method)
  • Events for Constructor:
    • afterUpload
  • Events for .insert():
    • start
    • data
    • readEnd
    • progress
    • pause
    • continue
    • abort
    • uploaded
    • error
    • end
• New isJSON property
• New callback in .insert() method:
  • .onStart - Triggered when upload is started and validations was successful
• New second argument in .insert() method:
  • autoStart {Boolean} - Start upload immediately. If set to false, you need manually call .start() method on returned class. Useful to set EventListeners, before starting upload
• New method on object returned from .insert() method:
  • .pipe() - Called with single argument: data {String} - Base64 string (DataURL). Can be used for data modifications, like encryption (see #35) or any other
• Partly move core to EDP, to avoid using .defer() and .setTimeout()
• New collection callback onBeforeRemove, allows you to check user and file itself before removing it
• remove() method now accepts second argument - callback function
• Important security updates
• Fix issue with empty file upload, now it ends with error: 400, Can't upload empty file
• interceptDownload - now supports file's subversions (passed as third argument)
• Overall fixes
