NS Site Cloner Native Support for WeDevs Project Manager

While currently the fix is to simply use NS Site Cloner Pro's options to deselect all the _pm_ tables, this is not applicable for the free version (and is a hassle with Pro). What we consistently see in the logs when trying to process the _pm_ tables is:

• SQL ERROR: Cannot drop table 'wp_15_pm_projects' referenced by a foreign key constraint 'wp_15_pm_invoice_ibfk_1' on table 'wp_15_pm_invoice'.
• FOR QUERY: DROP TABLE IF EXISTS `wp_15_pm_projects`
• ENTERING exit_processes

At this point the NS Site Cloner goes into a "exit and cleanup" process without actually doing anything. While the foreign key constraint is definitely a keyword, toggling on NS Site Cloner's "Skip Key Constraints" does not resolve the error. I've noticed in the NS Site Cloner changelogs where specific plugins have been catered to in the past. Hopefully the WeDevs Project Manager Pro suite receives this treatment.
