Add missing conferences to website

[rradczewski]

There is only one conference listed right now, the SoCraTes Germany in Soltau. It would be great to have all the other conferences on here too. Conferences follow a similar schema to the communities.

Lots of the conferences list their "Partner conferences" on their site:

• SoCraTes DE
• Codefreeze
• SoCraTes CH

Missing conferences (non-exhaustive)

• SoCraTes UK
• SoCraTes Canaries
• SoCraTes Italy
• SoCraTes Belgium
• SoCraTes Switzerland
• Codefreeze
• SoCraTes Day Berlin
• SoCraTes Day Linz
