Integration scripts for Clang's Modernize and Tidy tool.

New directory: `scripts/`, in which small scripts for developers reside. - `modernize`: runs all cpp files through `clang-modernize`, respecting out targeted compiler versions, applying C++11 transformations, doing syntax checks and formatting --- in parallel. - `tidy`: runs all cpp files through `clang-tidy`, with selected warnings only, since we do not want to warn on every small detail. Please check the talk slides for `clang-tidy` linked in the references!
