Similar series: update view to show similar series

[php-coder]

• view (src/main/webapp/WEB-INF/views/series/info.html) should be updated to show similar series. I see it as a new block with a list of the links to the similar series. This block should be placed below the series information.
• block should be visible on prototype (when you open this page in a browser, without a server)
• block shouldn't be visible by default (a new feature in the Togglz should be introduced)

Part of #967

@azorinmsu Hi! Do you have plans to continue to work on this issue?

block shouldn't be visible by default (a new feature in the Togglz should be introduced)

As part of this task, I'm going to use prototype-only comments in order to hide a new block from a rendering.
