Vote levels

[panta82]

b0f8606 removes hard-coded behavior that vote count must be hidden when the value is 0. This is now done through CSS.

Use case:

• Ability to disable the default behavior of hiding 0 votes (using CSS overrides)

The other two commits introduce the ability to attach custom classes on comments based on the number of votes. See the changes in documentation for more details.

Use cases:

• Red number when votes < 0, green when >0
• Collapse or gray out comments with many negative votes
• Award good comments with visual flair (eg. a different background color)

For some reason I wasn't able to make this work. I edited manually my embed.dev.js to match the proposed changes. Comments without votes do have the class isso-no-votes, but comments with votes do not get the class isso-vote-level-* (though the class isso-no-votes dissapears). What I may be doing wrong? Here is my embed.dev.js.

@pozitron57

Did you configure vote levels in the script tag?
As per: https://github.com/panta82/isso/blob/fd3f6f820d15e09153b89d9385a7443845425b6b/docs/docs/configuration/client.rst

Eg:

<script data-isso="/prefix/"
        data-vote-levels="-5,5,15"
        src="/prefix/js/embed.js"></script>

@panta82, Thanks for the reply, I was missing this configuration. I added it but it didn't help. Probably I messed something up while editing embed.dev.js, I'll look into it.

UPDATE

Now it should be data-isso-vote-levels, not data-vote-levels as I tried.
