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.

Single variable cannot have many values of different types. This also saves some memory, because union allocates memory just for one of its members.

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.

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.

Test and temporary version of compiler emiting PH7_OP_CLASS_INIT instruction.
However it works on ph7_class and thus passes whole class into the VM, what causes memory overhead,
as finally we have to find this class on the VM's stack. Instead, we could pass some ph7_class_info
structure containing a name of class to look for and information about its inheritances.
