Add support for Windows (#1374)

Initial support for Windows is implemented using the winpty translation
layer. Clipboard support for Windows is provided through the `clipboard`
crate, and font rasterization is provided by RustType.

The tty.rs file has been split into OS-specific files to separate
standard pty handling from the winpty implementation.

Several binary components are fetched via build script on windows
including libclang and winpty. These could be integrated more directly
in the future either by building those dependencies as part of the
Alacritty build process or by leveraging git lfs to store the artifacts.

Fixes #28.

 Alacritty is the fastest terminal emulator in existence. Using the GPU for
 rendering enables optimizations that simply aren't possible in other emulators.

 ## FAQ
 
-- **_Is it really the fastest terminal emulator?_**
-
-  In the terminals I've benchmarked against, alacritty is either faster, WAY
-  faster, or at least neutral. There are no benchmarks in which I've found
-  Alacritty to be slower.

-- **_macOS + tmux + vim is slow! I thought this was supposed to be fast!_**
+**_Is it really the fastest terminal emulator?_**
 
-  This appears to be an issue outside of terminal emulators; either macOS has an
-  IPC performance issue, or either tmux or vim (or both) have a bug. This same
-  issue can be seen in `iTerm2` and `Terminal.app`. I've found that if tmux is
-  running on another machine which is connected to Alacritty via SSH, this issue
-  disappears. Actual throughput and rendering performance are still better in
-  Alacritty.
