Fixed redactor capturing click events

[elis]

redactor was used to capture click events for adding a new block - I've added a redactorClicker element just after the original redactor and bound the redactorClicked event to the redactorClicker element instead of redactor.

Hi @elis, @natterstefan, @2277Dhruv
This fix won't work for the current version as we use the same click event to open external links (with Ctrl pressed).

I've made another one in #1252, can you try it for your use cases

#1252 seems to work, so I'm closing this PR
