Compatibility with PHP 5.5

I have done many updates to eA to fix compatibility in PHP 5.5.

* Updated ea_op_array with new functionality added in PHP 5.5.
* Optimizer has been removed.
* Project files for Visual Studio 6 and Visual Studio 2008 have been updated.
* Added gitattributes to force line endings of Win32 project files to CRLF.
