As per @zeffii suggestion (PR #1561) the IO tools were extended to export/import socket custom properties.
Note: This branch is branched off the socketExpander branch developed/discussed in PR #1561
With this addition the socket prop (used via use_prop) as well as newly added custom props (use_expander, use_quicklink and expanded) are exported and imported properly via gist.
More testing is necessary to prove it works in all case + better/more robust implementation + cleanup is needed. E.g. the exporting/importing of the socket “prop may have to be done via a proper serialize/deserialize prop method.
