libltdl missing from arts

While compiling trinity manually on arch I discovered that libltdl was removed from arts source tree. I got errors both on CMake configuration stage (http://paste.pocoo.org/raw/506509/) as on compilation stage (http://paste.pocoo.org/raw/504813/). Luckily i found on my HDD trinity code I pulled just before version froze and which I thought I deleted. After putting the missing libltdl dir into current arts dir both CMake configuration and compilation went without errors. Apparently libltdl from arts is not quite the same thing that is available in package form in most distributions main repos. As it is said in arts libltdl readme it has been slightly modified to make it work with KDE. As for now it should be put back in the arts, since miss of it prevents arts compilation.
