Code inclusion rework that include several changes (#58):
The build was successful. Ayrıntılar

* include() builtin function allows now to include a chunk of code, eg. a body of some loop
 * include() allows to load and execute file several times
 * require() still allows to include file just once and included file must have a valid OOP syntax
 * both functions will throw E_ERROR when impossible to include specified file
