* Fixed a bug when creating script objects - when the factory was executed, the execution nesting level did not increase, and if the constructor of the script object called the execution of the script function, it did not receive a free context for execution.
When compiling a script into bytecode, the initialization of the global variables of the script is no longer called.
Bug fixed - "scriptFile" was not available in the constructors of global script objects.
Improved script api dump generation - added output to the header file "operator XXX", casting to other types, added output of method's arguments name.
* Restore copyright.
* Change tabs to spaces. Update generated ScriptAPI.dox and AngelScriptAPI.h
Since the URHO3D_PCH build option is made available to support non-PCH build, our build system does not rely on precompiled header to include the Urho3D.h export header anymore. The export header is auto-included by one of Urho3D headers when it is required using the right format with the help of URHO3D_IS_BUILDING compiler define. As such, there is no need to explicitly include Urho3D.h in external project too. Sorry for the flip-flop.
It is now a library user own's responsibility to include the Urho3D.h in their source code. Or to include it as part of their own precompiled header similar to what Urho3D project has done.
The C Header file is intended to be 'force included' in the IDE to get content assist / code completion when editing AngelScript file in the C/C++ editor. The output section of DumpAPI() method is reordered slightly to keep the parser happy. This work is inspired by the work done by Vladimir Andri (see https://groups.google.com/forum/#!topic/urho3d/8WOOGAdwlEU).
Added note in documentation about lack of space between command line option and its parameter.
