Undelete (Restore From Trash) bulk Zoho Mail messages (more than 300 messages to restore).

zoho-mail-undelete-restore-trash-bulk.js

/* Javascript snippet for when you accidentially move thousands of emails to the Zoho Mail Trash and want to restore them
 *  Zoho only lets you restore up to 300 at a time, you can't select all.
 *
 *  This hacky javascript works around it.  Open Zoho Mail and go into the Trash, open the console with CTRL-SHIFT-J
 *  paste this in, and then it will just sit there hitting the select-all checkbox and then the restore button for gogoCycleCount times
 *  to restore 50 emails at a time.  Set the cycle count to however many emails you are restoring divided by 50.
 *
 *  DO NOT TOUCH THE ZOHO MAIL WINDOW WHILE IT IS WORKING, no checks are made that it is in the Trash folder.
