Fixed the updating iteration problem (hopefully)
made it so that a row cannot be edited if its status is complete or deleted, however the status is editable, if the status is changed then the rest of the row becomes editable
made it so that only valid iterations (iterations that are not over yet) are displayed in the dropdown menu
I recieved an error from JSON whenever I hit save (even if i didn't change anything) that caused the uploading to the server to fail, this might just be my computer but I am unsure
