- Update devel/luafilesystem from 1.5.0 to 1.6.2
- Make it support both lang/lua51 and lang/lua52

Note that previously this port downloaded it's tarball from github by a tag; unfortunately the developers failed to add a 1.6.2 tag to the repo, so the port will now fetch by commit id. Commit 5e55437, "Bump version to 1.6.2" [1] was chosen for this role.

The redports logs are at [2].
