- grunt: added `libsync` subtask which copies the files from any libraries registered as submodules into the local `lib/_/` directory so that they are always available, whether you have initialized the git submodules or not (gh-pages is one branch where the submodules will never be initialized by github, for example)

- updated the NPM packages (`npm-check-updates -u`)

- made sure the TinyColor submodule/library is also available, since the latest `spectrum` submodule (color picker) requires that one and does not keep an (old) copy of TinyColor embedded in itself no longer...
updated the 'synced' libraries.
