Added the Bidi iterator adapter, which applies a .rev() on construction if a given condition is true.

Added the RangeExt trait for making some operations on <R: RangeBounds<usize>> easier.

Added a FmtList type (and .fmt_list() method) which allows anything that can be borrowed as an iterator to render itself conveniently.

Added more pointer methods to Address, and created a system for working with references as well as pointers.

Add the comu module containing the type-system mutability tracking extracted from bitvec.

Added a background garbage disposal system in the wm module, under the garbage feature. It is accessed by importing the wm::BgDropExt trait and using its .bg_drop() method on a value.

The disposal system manages a single worker thread which receives any type and runs the appropriate destructor for it. Once initialized, the system remains in operation until explicitly shut down by the client program; once shut down, all future deferred-drop objects are destroyed in their local thread as normal.

This system allows programs to opt in to faster immediate behavior when a value goes out of scope, with minimal system and per-value cost.

Removed tap, pipe, and conv. They have been promoted to the [tap] crate.

Added conv::TryConv for fallible directed conversion.

Added fmt module, which supplies behavior to forward any formatting trait to Debug.

Removed pretty module in favor of fmt.

Fix typos.

Initial release, featuring:

• conv
• exit
• pipe
