package/alure: new package

Use the latest commit since there is no release since 1.2 (8 years ago).

While testing with test-pkg, the last build issue was
due to the gcc 4.8.3 compiler missing C++11 feature:
"std::list.erase(const_iterator pos) not implemented" [1]

arm-none-linux-gnueabi/include/c++/4.8.3/bits/vector.tcc:134:5: note:
no known conversion for argument 1 from '__gnu_cxx::__normal_iterator<const alure::Source*, std::vector<alure::Source> >'
to 'std::vector<alure::Source>::iterator {aka __gnu_cxx::__normal_iterator<alure::Source*, std::vector<alure::Source> >}
