Title: Add Voter.voted_up_on? and Voter.voted_down_on? methods.

This adds two more instance methods to Voter; `.voted_up_on?` and `.voted_down_on?`, which should be pretty self explanatory.

**Example**

```ruby
@user.likes @comment1
@user.dislikes @comment2
# user has not voted on @comment3

@user.voted_up_on? @comment1 # => true
@user.voted_down_on? @comment1 # => false

@user.voted_down_on? @comment2 # => true
@user.voted_up_on? @comment2 # => false

@user.voted_up_on? @comment3 # => false
@user.voted_down_on? @comment3 # => false
```
