Fixed problem with duplicate names ini entries.

parameters were not correctly initialized (issue #75)
argument names are probably always hard coded strings, so no reason to copy them to std::string objects, and now we also fix a memory corruption issue (issue #75)
extra check for existance of classname #77
calls to strlen has been converted into calls to ::strlen, because Php::strlen() now also exists as (slow) php function, see issue #78
