## Bug fixes
### get_estimated_block_num() returns results, when a block is missing

```
from beem.blockchain import Blockchain
from beem.block import Block
from datetime import datetime
print(Block(33898183)["timestamp"])
print(Block(33898184)["timestamp"])
```
returns
```
datetime.datetime(2019, 6, 18, 5, 8, 24, tzinfo=<UTC>)
datetime.datetime(2019, 6, 18, 5, 8, 33, tzinfo=<UTC>)
```
The time difference between block 33898184 and 33898183 is 9 seconds, which leads for timestamps between them to an infinite loop in `get_estimated_block_num`

This is fixed by checking of the `second_last_block_time_diff_seconds == block_time_diff.total_seconds()` in the while loop and returning the current block_num when true. This prevents infinite loops in which block_num jumps bewteen two values.
```
blockchain = Blockchain()
block_num = blockchain.get_estimated_block_num(datetime(2019, 6, 18, 5 ,8, 27))
print(block_num)
```
returns now 
```
33898184
```

## New Features
### Move the vote function to the Steem class
It is now possible to vote with the Steem class:
```
from beem import Steem
stm = Steem(keys=["xxx"])
stm.vote(100, "@author/permlink", account="voter1")
```
This allows it to vote without loading the content with Comment. A wrapper function was added to Comment, so that is still possible to use
```
from beem.comment import Comment
c = Comment("@author/permlink")
c.vote(100, account="voter1")
```

### Upvote and Downvote accepts only positive weights now
```
Usage: beempy upvote [OPTIONS] POST

  Upvote a post/comment

  POST is @author/permlink

Options:
  -w, --weight TEXT   Vote weight (from 0.1 to 100.0)
  -a, --account TEXT  Voter account name
  --help              Show this message and exit.
```
and 

```
Usage: beempy downvote [OPTIONS] POST

  Downvote a post/comment

  POST is @author/permlink

Options:
  -a, --account TEXT    Voter account name
  -w, --weight INTEGER  Downvote weight (from 0.1 to 100.0)
  --help                Show this message and exit.
```

So downvote accepts only positive numbers now. So it is not possible anymore to downvote with upvote() and to upvote with downvote().

## Update nodelist
The list of working node was update in Nodelist
```
from beem.nodelist import NodeList
nodes = NodeList()
nodes.get_nodes()
```
returns now
```
