Reslib : error in ressource path on android

[Madour]

The file path becomes incorrect when path is empty string.

NasNas/src/NasNas/reslib/ResourceLoader.cpp

Line 73 in fa80b14

auto file_path = path + "/" + file_name;

possible fix :

std::string file_path;
if (!path.empty())
    file_path = path + "/" + file_name;
else
    file_path = file_name;
