Yet Another Hacker News Extension Suite

There are two types of comment collapsing that are available: * Single-collapse: In this mode, comments are not all folded into one like other extensions because of the argument that this causes top-level comments to have too much importance and discourages discussion. Leaving the hierarchy in place but still collapsing the contents of the comments is an attempt at finding a working middle ground for this issue. * Multi-collapse: In this mode, comments are all folded into one, much like RES. More to come in the future.
