Comment reactions

[colelloa]

Add reactions to issue comments

-change data model, add reaction fields to issue_comments table
-alter paged_api_request in api_client.rb so that it can handle different media types
-alter ensure_issue_comment in ghtorrent.rb so that it inserts new fields or updates fields if necessary
-alter retrieve_issue_comment in retriever.rb so that it uses the media type necessary to get the reaction fields

• add Sequel.split_symbols = true to db connection to quell deprecation warnings ***this line may not be necessary given most recent commits to master

still awaiting resolution of #52 before able to fully test

Hi @colelloa, thanks for fixing the bug in full_repo_retriever.rb. I 've backported your fixes to master and put them in production; it was necessary as we where loosing events. You will get a conflict if you sync to master.

The Sequel.split_symbols = true line should be redundant now.
