[texworks] shared library for synctex

[Atsuhito Kohda]

Hi all,

I got a bug in Debian which claimed texworks should use
the shared library for synctex (Bug #753818).

I'm not sure if this applies to the upstream or not but
I'd like to report it here in case this is an issue of 
the upstream too.  
I want to remove Debian specific modification as possible as 
I can so  please consider if this applies also to the upstream.

I attach an patch (I removed Debian specific so irrelevant 
parts).

Thanks in advance.  
Best regards,				2014-7-9(Wed)
