Save Refund ID properly in POST META

[kkotha82]

I am writing a custom plugin for Exchange / Return for WooCommerce. I am supporting automatic refunds of returned products by linking up with WC refund module. The Refund ID is only being saved in the order comments. Please save the Refund ID in post meta properly so plugins like mine can easily access the same.

@kkotha82 I have added a custom hook #142 which is not yet to merged.

@kkotha82 you can use that hook to fetch the refund id for the order you want on the go.
