CC: Split the profile history link into 2 links

Before there was a single link which pointed to the post history in all
forums. As this sometimes takes a long time to load, this commit splits
it into 2 links:

* A link to the post history in the current forum (loads faster)
* A link to the post history in all forums (loads slower)
