Include OTA links for older Android security releases

[WanderingGlitch]

Would be handy to have more than just the current month's OTA links. An exhaustive list may be overkill, so maybe just include the previous month's links along with the links for the current month ?

That's an interesting idea. As far as I can see it, each release for Nexus devices includes:

• stock firmware images
• OTA updates
• proprietary binaries
• AOSP source (including kernel)

Today we really only cover AOSP source with changes.droidsec.org
