Mark method/closure call frame as active.
The build was successful. Details 
It is impossible to dump the frame during its initialization, as it does not contain all necessary information. Such frame should be skipped. After initialization is done, the frame has to be marked as active just before
evaluating a function body.

Store float values in an union.
The build was successful. Details 
Single variable cannot have many values of different types. This also saves some memory, because union allocates memory just for one of its members.

Remove error_log() builtin function and corresponding PH7_VM_CONFIG_ERR_LOG_HANDLER.
The build was successful. Details 
It was not fully implemented and such feature should be implemented in separate module or on developers own.

Aer does not support custom error handlers.
The build was successful. Details 
Errors are used only internally to emit notifications about compilation/execution problems. They should not be catched and handled by custom handlers, but properly configured (to be displayed or logged). Instead developers should
use exceptions that can be catched with try-catch block.

VmExtractDebugTrace() provides information about a kind of call.
The build was successful. Details 
Both VmExtractDebugTrace() and VmDebugTrace structure should provide information whether it was object call or a static method call.

Enable debugging.
The build was successful. Details 
This commit introduces ne debug feature. The PH7 Engine limits the VM dump to the global scope. Since Aer Script is fully object-oriented language the dump option contains only information about last call of OP_DONE. This change,
forces the VM to store all instructions set in a global container when debugging is enabled, thus providing information the dump of whole script parse.

New memory subsystem.
The build was successful. Details 
This is a new memory subsystem implementing heap calculations as well as new builtin functions:
 * get_memory_usage()
 * get_memory_peak_usage()
 * get_memory_limit()
It also allows to set an upper memory limit, ensuring that processed script will not be able to allocate more memory from OS.
New subsystem is based on work done in 'memory_limit' branch. Big thanks to devnexen!
This finally fixes #25.

There is no need for include_once() and require_once()
The build was successful. Details 
Aer is object-oriented language and the code it includes is executed in the global scope. Global scope can contain only classes and namespaces and they cannot be re-declared. Thus every file can be included just once. We can
leave this to programmer, or take care about it on interpreter side. With this commit, include() and require() builtin functions allows to load file just once. Thanks to that, there is no need for include_once() and
require_once(). Done in scope of #30.
