🎨 improve gulp dev reload behaviour (#7543)

refs #7427
- prevent unnecessary reloads of the server due to changes in client files, this makes working on the client as quick/painless as the old `grunt dev` command
- fix nodemon `watch` config - it only accepts directories not files
- update nodemon `ignore` config - directories should be specified without a `/*`, add directories that are changed on each client re-compile
