* Added the ability to update config settings from env vars

variables
* Refactored the config get() methods to use toml-query
* Made the `Updateable` trait more generic
* Added a mechanism for creating alternate backends
* Added a CmdRenderer and the ability to have multiple renderers
* Made MDBook::load() autodetect renderers
* Added a couple methods to RenderContext
* Converted RenderContext.version to a String
* Made sure all alternate renderers are invoked as `mdbook-*`
* Factored out the logic for determining which renderer to use
* Added tests for renderer detection
* Made it so `mdbook test` works on the book-example again
* Updated the "For Developers" docs
* Removed `[output.epub]` from the example book's book.toml
* Added a bit more info on how backends should work
* Added a `destination` key to the RenderContext
* Altered how we wait for an alternate backend to finish
* Refactored the Renderer trait to not use MDBook and moved livereload to the template
* Moved info for developers out of the book.toml format chapter
* MOAR docs
* MDBook::build() no longer takes &mut self
* Replaced a bunch of println!()'s with proper log macros
* Cleaned up the build() method and backend discovery
* Added a couple notes and doc-comments
* Found a race condition when backends exit really quickly
* Added support for backends with arguments
* Fixed a funny doc-comment
* Prohibit 'print.md' files
Fix#258 by emmiting an error whenever an mdBook contains a
"print.md" file in its root.
* Apply suggested changes
* Add tests
* Implement partial include of source files.
The macro `{{include some_file}}` accepts now optional line number
arguments, s.t. the specified line range is included. The following
forms are supported:
* `{{include some_file::}}` is equivalent to `{{include some_file}}`
* `{{include some_file:from:}}` includes lines [from, infinity)
* `{{include some_file::to}}` includes lines [0, to]
* `{{include some_file:from:to}}` includes lines [from, to]
* Remove the special case IncludeFull which is IncludeFrom(0).
* Use Range, RangeFrom, RangeTo and RangeFull to represent include-ranges.
Also:
* Move out introduced methods as free functions.
* Introduce RangeArgument trait as long it is unstable in stdlib.
* Use itertools for joining of lines on the fly.
* Split tests.
* Simplify include file argument parsing.
* Make utils::string private and link collections_range feature issue.
* Use japaric/trust for travis configuration
* Moved the github pages logic (not running the script breaks the build)
* Removed the x86 linux musl build
