Auto-upgraded all sub-project dependency versions plus added a master project file and shell script for upgrades

If you like, this would make it a tad more comfortable to upgrade the samples, users can do this themselves by a mere `bash upgrade.sh`.

Project file is to hold the `:sub` vector of subprojects and `lein-ancient` + `lein-sub` plugins. The shell script pulls in the plugins/deps, then upgrades all projects and finally pulls in all new versions of dependency archives.

(p.s. not sure if the CA applies here too... I got one printed so I'll send it soon I guess)
