#177 Upgrade smarty engine to 2.6.10

[greyhair]

I'm developing a gallery 2 xoops module for
xoopsgallery.org. I have things working IF i replace
the current xoops smarty engine with the latest smart
engine (v 2.6.10).

Here is what needs to be done (as far as I can tell)

1. rename smarty directory
   /class/smarty --> /class/smarty.old

2. copy the lib directory from smarty.php.net download
   to create:

/class/lib <-- the lib directory from the
Smarty-2.6.10.tar.gz contains the smarty "engine".

1. rename lib to smarty to have
   /class/smarty

2. copy index.html from /class/smarty.old to /class/smarty

3. If everything you have works as expected (mine has)
   delete /class/smarty.old.

In addition to helping me out, the update does fix some
security issues within the "engine" its self.

Thanks for your consideration.
