Architect update: A.J. Kropholler

The page about architect A.J. Kropholler has had a major overhaul, and his biography is mostly rewritten and expanded drastically. Also, the pages about three of his most important churches were similarly treated; the O.L. Vrouwe van Lourdeskerk in Scheveningen, the O.L. Vrouw van Goede Raad in Beverwijk and the H.H. Martelaren van Gorcum in Amsterdam. A page with interior pictures of the latter church was also added.
