[Developers] Adding a webpage to a topic.

[Alec Flett]

/common/webpage instances are not supposed to be shared - they're like  
any other Compound Value type in that sense. You should create a new  
one for each topic that wants to link to that url.

So really it would be best if you used "create": "unconditional" (or  
maybe "create": "unless_connected", which really does what you want)
