move postAjax function into a new file
big rework of error handling on requests
- central point for checking for 'error: "out of date"' response from server
- in 'out of date' state, an error dialog is shown and no further requests are sent to the server
- request queue has central point for request adding - now request count is accurate, not just for COMM requests
- request error count is cleared after a period of no requests failing
map data requesting: the stock site no longer performs unlimited retries on 'error: TIMEOUT' map data tiles, so update IITC to match
split tiles that are retried into smaller requests - might help things at the server side??? no harm in it...
version check plugin - use https URLs for version check when intel loaded over https

If it doesn't work, try to delete the file "uniques[uniques]" in your Google Drive. Be sure to delete it from the trash as well.
