imacros code to automatically delete facebook messages

facebook_messages_delete_imacros.iim

'these notes can be removed'
'this script requires the free chrome imacros plugin to run (http://imacros.net/overview)'
'updates to facebook messenger interface will likely break this and it will need to be rebuilt using a new recorded imacro.'
'i tested this on windows 10 using the most updated chrome browser (stable) as of 14/1/2017, future updates may break this.'
'i recommend copy-pasting the delete code as many times as you want to delete in one sitting. I did 20 at a time.'
'i also recommend using "play loop" and setting a loop according to the number of messages you have to delete. The messager page will reload on every loop.'
