Also adds a feature `err-println` for enabling `err_println!` printing.

commit bdd21810882dbba8485ac44c871482dfc6ea9b93
+Author: Joe Wilm <joe@jwilm.com>
+Date:   Sat Nov 19 16:16:20 2016 -0800
+
+    Add support for recording/running ref tests
+    
+    Ref tests use a recording of the terminal protocol and a serialization
+    of the grid state to check that the parsing and action handling systems
+    produce the correct result. Ref tests may be recorded by running
+    alacritty with `--ref-test` and closing the terminal by using the window
+    "X" button. At that point, the recording is fully written to disk, and a
+    serialization of important state is recorded. Those files should be
+    moved to an appropriate folder in the `tests/ref/` tree, and the
+    `ref_test!` macro invocation should be updated accordingly.
+    
+    A couple of changes were necessary to make this work:
+    
+    * Ref tests shouldn't create a pty; the pty was refactored out of the
+      `Term` type.
+    * Repeatable lines/cols were needed; on startup, the terminal is resized
+    * by default to 80x24 though that may be changed by passing
+      `--dimensions w h`.
+    * Calculating window size based on desired rows/columns and font metrics
+:
      required making load_font callable multiple times. I think this still
+:
      needs to be done for linux.
+:
    * Refactor types into library crate so they may be imported in an
+:
      integration test.
+:
    * A whole bunch of types needed symmetric serialization and
+:
      deserialization. Mostly this was just adding derives, but the custom
+:
      deserialization of Rgb had to change to a deserialize_with function.
+:
    
+:
    This initially adds one ref test as a sanity check, and more will be
+:
    added in subsequent commits. This initial ref tests just starts the
+:
    terminal and runs `ll`.
