Generalized directories, nix/mac maven opencv jar

Generalized the directories to look in {project}/resources/images rather
than one one person's {project} directory. Works on any operating
system.

Moved dlls into appropriate windows folder.
Moved loading OpenCV native libraries into single method, only
implemented Windows, have not yet implemented nix or os.
Added Maven download of 2.4.9 OpenCV java bindings that includes
pre-built OpenCV libraries for nix and Mac systems. But not windows,
they have to be loaded by manually accessing {project}/lib/windows/x86
in the new OpenCV#Load() method.

Removed IntelliJ specific .xml file for loading the opencv libraries.

Changed all the in/output test files to have no spaces. Underscores
instead.
