Link to in html

[davydovanton]

Fixed #48
Also I fixed case when html helper called inside another html helper. For example:

html.div do
  span 'hello'
  html.div { span 'hanami' }
end

/cc @hanami/core-team

@davydovanton @joneslee85 I'm reverting this, this implementation is too cluttered and reimplements link_to inside HTML builder.

@jodosha no problem. But do you have any ideas how I can solve this problem?
