Quick fix to install and uninstall dashboard modules in Opencart 188.8.131.52.
Also fixed last module not displayed if a row width sum isn't 12.
Two version available:
- Hard-coded (overwrite two admin side files - no vQmod needed)
- vQmod (vQmod needed)
Is a "quick" fix because there are others issues that could be improved for this feature. (remove data on uninstall, set default sort order if not inserted, serialize data stored in setting table)...however, it should works. I tested it only on Opencart 184.108.40.206, I don't know if this problem is present even in others 2.3 versions...maybe let me know.
