Treat code block like a single paragraph

[akarzim]

It would be great to have the ability to treat code blocks like a single paragraph.

this is a paragraph

```
# no blank line after backticks

def code_bock
  puts "this is a code block"
end
```

~~~ruby
puts "tilde and language name should be allowed too"
~~~ 

this is another
paragraph

There are two different code block syntaxes in this example.

I'm not sure that g:limelight_bop and g:limelight_eop can do the job…
