improve library loading

[GoogleCodeExporter]

Currently, the library is only found and loaded, when the lib is called 
"libpl.so" and found by CDLL().

Improve this by using find_library() and on linux maybe even pkg-config. Also 
use "libswipl.so" since new versions install it like this.

Is this issue fixed?

With revision 111 pyswip finds /usr/local/lib/libswipl.so

In INSTALL perhaps we should change the symbolic linking line:
- $ sudo ln -s  /usr/lib/pl-5.6.34/lib/i686-linux/libpl.so.5.6.34 /usr/lib
/libpl.so
+ $ sudo ln -s /usr/local/lib/swipl-5.10.5/lib/x86_64-linux/libswipl.so.5.10.5 
/usr/local/lib/libswipl.so

I just committed a modification that should solve this issue in most cases 
(including the one that Stancomb gave).

It definitely works on Windows XP 32, Fedora 16 32 bits and Ubuntu 12.04 32 
bits (though Ubuntu still has some other problems).

After I solve issue 1, I will have this also tested in the 64 bit versions of 
the above distributions/OSes.

Commit r120 is supposed to solve this issue.

Corrected in r122. If there are issues with MacOS, it will be treated in a 
different issue.
