Add trophy case to README

[Shnatsel]

It's important for collaborative projects to show progress, as it motivates further participation. To that end we should surface the crates already audited and/or cleansed in the README.

[Lokathor]

yes plz add the randomize-3.0 crate <3

[Shnatsel]

Here's what I think it could look like:

---

libflate

Discovered and fixed a security issue plus 3 non-expoitable safety issues. Reduced number of unsafe blocks in the crate from 16 to 1, two of which were replaced with shared dependency crates. More info

---

Or we could go for a more structured format, such as:

Crate	Unsafe blocks before	Unsafe blocks after	Security issues found	Comments	Tracking issue
libflate	16	1	RUSTSEC-2019-0010	Also fixed 3 non-exploitable memory safety issues	#1

Thoughts?

@oyvindln would you be OK with your recent work on miniz_oxide being showcased on this repository?

[Lokathor]

that table format looks crazy bad on mobile display. Let's stick to paragraphs which will reflow to smaller screens easily.

[Shnatsel]

On the other hand I really like the structured presentation that provides an overview at a glance. https://github.com/rust-fuzz/trophy-case just goes down that route and doesn't care about mobile.

Perhaps we could strike a middle ground with bullet points? How about this:

---

libflate

• Unsafe blocks before: 16
• Unsafe blocks after: 1 plus 2 more moved to shared crates
• Security bug found: RUSTSEC-2019-0010
• Tracking issue: Audit libflate #1

Also discovered and fixed 3 non-expoitable safety issues.

We should probably also credit the people who performed the audit. Attribution is important and also helps motivate contributors.

@Shnatsel sure

Added initial version in #23. Please add your contributions!
