Before there was a button to "quickly" add the untrusted domain to the config. This button often didn't worked, because the generated URL was often untrusted as well. Thus removing it and providing proper docs seems to be the better approach to handle this rare case.
Also the log should not be spammed by messages for the untrusted domain accesses, because they are user related and not necessarily an administrative issue.

Adds a little button to the trusted domain warning, if an admin clicks on the warning he will be redirected to ownCloud and asked whether he want to trust this domain.
By far not the cleanest code, or clean at all, but does the job and I don't see a reason to make a lot of changes for this little improvement.
