* Fix double execution in Code demo
PR #5037 fixed double execution of the run button on mobile. But the link button and other events still suffer from double execution. This PR moves the fix from the run button to the central bind function so that it applies universally.

Not used but good to have.

By default http-server will serve ./public if it exists. We

* Fix error conditions for setParent #4989
* Error now thrown when calling `a.setParent(b)` on non-null b if the output/previous connection of a is not connected to an input/next connection of b without removing block from old parent's child list.
* Commented out error for when calling `a.setParent(null)` if a is connected to superior block.
* Adjusted comment to reflect that blocks were no longer being disconnected in this method.
* Also changed == to === per #4924 (`newParent` and `this.parentBlock_` must both be instances of `Blockly.Block`).
