Merge lp:~michihenning/unity-scopes-api/registry-noise into lp:unity-scopes-api

[Michi Henning]

Removed a bunch of noise that was logged by the registry if the scope installation dirs contained unexpected files or files without permission.

Simplified FindFiles.cpp by using boost::filesystem instead of dirent.

Looks good. We need to make sure it doesn't cause any regression with broken click scopes (such as sbbscope - swiss transport scope). +1
