Normalize people's name/surname case sensitivity

[Zubyte]

Some people send their application form with the name or surname fields in UPPERCASE. After the interview and acceptance of a candidate, the name is transferred to the crauto with the same format, which is obviously undesirable.

This could be fixed normalizing the name before saving it to the database of the WEEEHire. Special care should be taken for surnames with an apostrophe inside, as the part following it should have a capital letter too, but this is a further optimization.
