Fixed notifications and a couple bugfixes

This fixes a few bugs / tweaks with Kandan that were bugging me
This isn't immediately apparent, but local kinda messes things up. When we submit an activity up, it is local initally, and then not local (after the message posts to the server and is returned back). What this means is that if you post a message, and switch tabs real quick (before you get a response back from the server), you can get a notification and a sound because it is triggered by this. Instead, while we should show messages in the app if we post from a different browser for example, I think its fair that we don't do a noise or change the number of messages in the title, since we know what we said. This is also the easiest solution as well.
