#80 PHPinfo() displays DB engine, CCI(libcas) and PHP driver's version info

[Jira Trac]

When phpinfo() is called, it would be good to see not only DB engine version but also our cci library's version and PHP driver's version.

A new user never knows why CUBRID php driver dynamically linked with libcas.so.
A new user never knows how often they have to upgrade engine to a new version.
A user in XE team has suggested this idea, when he upgrade several times DB engine(we releases new versions and patches a lot), he forget to check version info of cci and php drvier.
