*Title: Transfer data on the Secure Sockets Layer(SSL port 443) with eZSOAPClient.

*Incentive: 
Currently eZSOAPClient is transmitting data using soap without SSL.
The current era is loocking for security and SSL is found the most suitable
protocol for transmitting secure private document via internet. Thus we are
implementing SSL with soap for the most secure transmission of data.

*Documentation: 
eZSOAPClient can transfer data with SSL and without SSL now. If the port is
mentioned as 443 or just the string 'ssl' then this class will consider that
transfer using SSL protocol, otherwise the transfer will be consider as a normal
transfer. Even after enhancement with SSL still it will work with previous
versions of eZ Publish with normal soap transfer of data also.

CURL library function is used for SSL transfer so it needs to install curl package
7.0.2 or above and recompile PHP with option --with-curl='PATH' to use this feature.
