Title: Using submodules for external repositories

This commit removes the CodeMirror 2, CSSMin, JSMin, JQuery, and JQuery-UI-Touch-Punch libraries from the repository itself, and replaces them with Git submodules (with the exception of JQuery, whose minified form gets downloaded directly from the JQuery website). This greatly reduces the number of files the repository tracks. To recreate these packages in the repository, run ``make`` from the root directory.
