removed all zend dependencies from the public extension object, and moved it into the src directory
refactored code, so that there is no zend engine dependency left in base.h header file
fixed test
moved init.h from header files to src directory because it is zend-specific
refactored parameters class so that no zend engine dependency is necessary in the include files
the exception.h header file no longer depends on the zend engine header files. TSRM macros are no longer used in any of the public PHPCPP header files so there is no more need for the phpcpp/config.h header file nor the config-create script
renamed src directory to zend directory, disabled TSRM debug code
