Add type to supports data

The Issue

Currently, when you list claim information (claim_list_mine/claim_show/resolve/claim_list) that shows supports, you can't tell if it's a classical support or a tip. We should add a type attribute to each support. If someone sends a tip to themselves, it's treated the same way as a classical support, so not sure which way it needs to be captured.

This will be an important field to report of off for search results and have available in the block explorer.

Expected behaviour

Support should show if it's a tip or not

Actual behaviour

Can't tell if support is a tip or classic support
