Add structopt dependency in version 0.3.7

This patch series replaces argparse with structopt in the argument
handling code. As a first step, we need structopt as a dependency.

+- **[breaking change]** Macro now generates [associated constants](https://doc.rust-lang.org/reference/items.html#associated-constants) ([#24])

+## How to update your code to use associated constants
+Assuming the following structure definition:
+```rust
+bitflags! {
+  struct Something: u8 {
+     const FOO = 0b01,
+     const BAR = 0b10
+  }
+}
+```
+In 0.9 and older you could do:
+```rust
+let x = FOO.bits | BAR.bits;
+```
+Now you must use:
+```rust
+let x = Something::FOO.bits | Something::BAR.bits;
+```
+
+# 0.9.1
+- Fix the implementation of `Formatting` traits when other formatting traits were present in scope ([#105])

+
+- Printing an empty flag value with the `Debug` trait now prints "(empty)" instead of nothing ([#85])
+
+- The `bitflags!` macro can now be used inside of a fn body, to define a type local to that function ([#74])
