Store releases announcements into this git repository

Could be into this repository, but in the website repository it would make more sense. As we have to store images, and this could be displayed on a blog, changelog page.

• v0.11.{1,2}
• v0.8.1
• v0.8.0 Release (!145 - merged)
• Silkaj v0.7.x releases: DuniterPy
• Silkaj v0.6.x releases: Let’s install
• Silkaj v0.5.0 release: Let’s certify!
• Silkaj v0.4.0 release
• Silkaj v0.3.0 release: Let's send money!
• No announcement for the v0.2.0: just a changelog, the announcement was done in the v0.3.0 looks like
• Silkaj: new CLI Duniter client
