Add about page

[ferbsx]

This should be approved by all organizers.

• What is our mission?
• Who we are? > explain the name and why the name change briefly
• Who is our audience?
• mention current organisers
• mention how people can help us (funding/ contribution/ coaching/ organizing)
• link to our events page / mention the latest/ upcoming event

[ferbsx]

This still needs to be updated with:

• German translation of the whole page
• Add link to sponsoring packages page (not existent yet)
• the jekyll layout needs to be adjusted so that on the header it says about and the page title stays What is code curious? (@shushugah is going to do this)
• It would be great if the next event was shown somewhere on the page (with the link to the event), this needs to be coded so we wouldn't have to update this every time a new event is announced.

Do you want to show the next few events? For example the 3 latest events or something? They would be updated during compile time, so for example when a new event is added...then we can add new events

[ferbsx]

yes! Such a thing would be great :)

See #47 for custom header_text, the home page previews latest upcoming event
