* Allow underscores in the link type name
* Add some tests for include anchors
* Include parts of Rust files and hide the rest
Fixes#618.
* Increase min supported Rust version to 1.35
* Add a test for a behavior of rustdoc_include I want to depend on
At first I thought this was a bug, but then I looked at some use cases
we have in TRPL and decided this was a feature that I'd like to use.
* Created regression tests for the table of contents
* Refactoring to make the test more readable
* Fixed some bitrot and removed the (now redundant) tests/helper module
* Removed the include_str!() stuff and use just the dummy book for testing
* Regression tests now pass again!
* Pinned a `*` dependency to use a particular version
* Made sure test mocks return errors instead of panicking
* Addressed the rest of @budziq's review
* Replaced a file open/read with file_to_string
