Subscriptions can't be added if user has zero subscriptions existing, can't see random or all in blab list

[jonathanvaughn]

Figured out why I was having the problem, sort of. TL;DR: The add blab logic was inserting at the start of the list, but that didn't work if there wasn't any list ...

Here's my fix for that, plus removing the minimum of 3 blabs restriction (not sure why that was there, but I only had 3 I was testing with so that was annoying), and fixing the all and random blab links to work even if user has zero subs (when logged in and no subs, wouldn't even get the random and all options).
