A functional rustls-cert-gen with basic parameters.

This is basically #185 minus #188 and #189. The structure also differs
as sub modules have been inlined in `main.rs` and `cert.rs`. `anyhow`
has also been added as a dependency to replace the `Result` alias.

Closes #175

+# rustls-cert-gen
+
+`rustls-cert-gen` is a tool to generate TLS certificates. In its
+current state it will generate a Root CA and an end-entity
+certificate, along with private keys. The end-entity certificate will
+be signed by the Root CA.
+
+## Usage
+Having compiled the binary you can simply pass a path to output
+generated files.
+
+	cargo run -- -o output/dir
+
+In the output directory you will find these files:
+
+  * `cert.pem`  (end-entity's X.509 certificate, signed by `root-ca`'s key)
+  * `cert.key.pem` (end-entity's private key)
+  * `root-ca.pem` (ca's self-signed x.509 certificate)
+
+For a complete list of supported options:
+
+	rustls-cert-gen --help
