Expansion to the capital of Finland

Company name is changed due to stakeholder transition to Ahonen-Ilveskoski

After the early years graduate engineer Reino Ilveskoski joined Kalevi Ahonen as a new stakeholder. The engineering office started using the handy abbreviation AI, which stuck as a lasting part of the identity.
