#### Expected behavior
The utopian-moderator extension should show the current utopian-io voting power


#### Actual behavior
![screenshot.png](https://res.cloudinary.com/hpiynhbhq/image/upload/v1518783521/ze9xsp0vrhogxowgvzkz.png)

The extension shows the utopian-io voting power at the time of the last utopian vote. The `voting_power` field in the steem account information only stores the VP at the time of the last vote, not the current value:

```python
>>> from steem.account import Account
>>> a = Account("utopian-io")
>>> a['voting_power']
6680
```

In order to get the current VP, one has to calculate the voting power regeneration since the last vote. Here's the python-equivalent to get the current voting power:

```

def get_voting_power(account):
    """get current voting power. The 'last_vote_time' value in the account
    data only contains the VP at the time of the last vote.

    """
    last_vote_time = parse(account['last_vote_time'])
    diff = (dt.datetime.utcnow() - last_vote_time).total_seconds()
    regenerated_vp = diff * 10000 / 86400 / 5
    total_vp = (account['voting_power'] + regenerated_vp) / 100.0
    if total_vp > 100:
        total_vp = 100.0
    return total_vp
```

#### How to reproduce
Compare the value in the extension with those on steemd/steemworld/...

Here is the corresponding part in the code:

@justyy, steemtools seems to be affected as well:
