I'm working heavily with steem-python. (1, 2, 3, 4, 5)

What I needed in my latest steem project is to make delete_comment operations via steem-python but unluckily it wasn't implemented.

steem-python covers most of the blockchain operations but it's missing some of them.

Missing operations in steem-python

After seeing delete_comment is not implemented, I quickly implemented it in my version of steem-python. After initial tests, it works fine.

Usage

s = Steem(
    nodes=["RELIABLE_RPC_NODE"], 
    keys=["POSTING_KEY"]
)
c = Commit()
c.delete_comment("emrebeyler/testpost", account="emrebeyler")

Note that, first parameter is the identifier convention steem-python uses already. it's $username/$perm-link.

Unit tests

Also, added related unit tests and they ran perfectly fine. Waiting for upstream review.
