Additional endpoints for SteemPlus backend
We have added three new endpoints to help us get data from SteemSQL, for a better flexibility in our extension. It might look like there is not much code behind this update, but I can guarantee that the complex SQL request kept us sweating for a good while.
New Features
Here are the new routes pushed in this update:
/api/get-received-witness-votes/[username]: Get all the votes received by a witness along with a timestamp, voters Vests and Proxied Vests, for further filtering and sorting.
Result for @stoodkev
[{"timestamp":"2018-03-12T19:35:39.000Z","account":"ahugehug","totalVests":1741.36062,"accountVests":1741.36062,"proxiedVests":0}, ...]
/api/get-incoming-delegations/[username]: Gets incoming delegations for @username. It returns a timestamp, the names of delegators, and the number of Vests being delegated.
Result for @stoodkev
[{"delegator":"steem-plus","vesting_shares":1026195.2327,"delegation_date":"2017-11-30T18:29:48.000Z"}, ... ]
/api/get-wallet-content/[username]: Gets the 500 last items from @username's wallet, including incoming and outgoing transfers and claimed rewards.
Result for @stoodkev
[{"timestamp":"2018-04-23T09:58:27.000Z","reward_steem":0,"reward_sbd":0,"reward_vests":0,"amount":110.276,"amount_symbol":"SBD","type":"transfer_to","memo":"","to_from":"steem-plus"}, ... ]
Additionally, in order to protect the API from abuses, we implemented express-rate-limit. It allows us to control the maximum number of calls to the API possible from the same IP address during a certain timeframe.
Commits

Thank you for your contribution. @steemsql is not free anymore and thus we should be very careful in this as this potentially will make the API server a proxy between users and steemsql.
However, as I understand this, it is useful to separate logics from the presentation, as you are using the APIs in Chrome extension, thus intelligent users may view-source and get the API directly.
On here, line 86, you are missing a (NOLOCK) which might impose load to the steemsql server. And I am not sure this is the 'correct' way to get incoming delegation as you are making assumptions that the ID increases as the timestamp increases. You might want to look at alternative solution such as here
