1.1.0

Fixed running concurrent jobs after add/cancel changes.

1.0.6

• Added compiled version of src folder for require/import usage
• When adding/canceling item, the queue start will wait until no add/cancel is called - this will prevent loading all entries when using scrolling (item is visible and then canceled - removed from view). The time can be changed when constructing queue.
• Improved situation when adding same url to a queue - all the callbacks will be called and only single load request will be created.
