contrib: add dev script

This patch adds a fairly contained dev script that almost doubles as an integration test if you squint hard enough.
It runs an isolated instance that we can add more things to, it at least seems handy to me for quickly testing how changes affect e.g. the web UI, RSS feed, etc.

+# dev script
+
+`go run ./contrib/dev/`
+
+If you want to instead use this to bootstrap:
+
+1. `go run ./contrib/dev/ --cleanup=false`
+2. Note the tmp dir printed out
+3. Stop the program `Ctrl+C`
+4. Modify as needed within the tmp dir
+5. Run `git-dir` and point at the config contained within the tmp dir
+6. Remember to clean up the tmp dir yourself when finished
