remove statistics submodule

The way the trackers worked was rather... "adventurous", and while there
were some good ideas and it mostly worked, the implementation and
interface could do better.

Additionally, it was incomplete, for example there were a lot of
mechanics just missing.

While I'm not against having this functionality provided by evtclib, I
think it would be more worthwile with a better designed implementation &
API, so this "proof of concept" implementation is gone until there is a
better way of doing things.

gamedata is being kept, as the boss identifiers are useful and
applications shouldn't have to deal with keeping this low-level list
themselves.

-///
-/// This basically simulates a single boon-queue (for a single boon).
-///
-/// # A quick word about how boon queues work
-///
-/// For each boon, you have an internal *boon queue*, limited to a specific
-/// capacity. When the current stack expires, the next one is taken from the
-/// queue.
-///
-/// The queue is sorted by boon strength. This means that "weak" boons are
-/// always at the end (and as such, are the first ones to be deleted when the
-/// queue is full). This prevents "bad" boons (e.g. the Quickness from Lightning
-/// Hammer #2) to override the "good" boons (e.g. the Quickness from your
-/// friendly neighborhood Chrono with 100% boon duration).
-///
-/// This also means that boons can be "lost". If the queue is full, the boon
-/// might not get applied, or it might replace another boon, thus wasting some
-/// of the boon duration.
-///
-/// Intensity-stacked boons (such as Might) work a bit differently: as time
-/// passes, all stacks are decreased simultaneously! As soon as a stack reaches
-/// 0, it is dropped.
-///
-/// You can find more information and the size of some of the queues on the wiki:
-/// https://wiki.guildwars2.com/wiki/Effect_stacking

-//! The idea behind a "tracker" is to have one object taking care of one
-//! specific thing. This makes it easier to organize the whole "statistic
-//! gathering loop", and it keeps each tracker somewhat small.
-//!
-//! It's also easy to define your own trackers if there are any statistics that
-//! you want to track. Just implement [`Tracker`](trait.Tracker.html). It
-//! doesn't matter what you track, it doesn't matter how many trackers you
-//! define.
-//!
-//! If you want to track stats separated by player or phases, consider writing
-//! your tracker in a way that it only tracks statistics for a single player,
-//! and then use a [`Multiplexer`](struct.Multiplexer.html) to automatically
-//! track it for every player/agent.
-//!
-//! You can use [`run_trackers`](../fn.run_trackers.html) to run multiple
-//! trackers on the same log.
