Migrating from WIndows to Linux fails, no image shows

[sgornick]

Brief Description: After migrating from Windows to Linux (or vice-versa), the products for a store will not be shown.

Here's a user report of this occurring: https://openbazaar.slack.com/archives/support-linux/p1468348222000085

The workaround for this issue is to update the hashmap table and set the directory separator to be of the type that matches for the platform (i.e., "/" for Linux, "" for Windows.) Of course, this should only be done after first backing up the data directory.

sqlite3 OB-Mainnet.db "update hashmap set filepath = replace(filepath, '\', '/')"

I'm creating this project Issue so that this bug can be found by anyone troubleshooting, and also so that it is tracked until fixed.
