Gradlefy web

Making this a gradle project that dynamically depends on dbi and common. Can be run with autoreloading Jetty on command line like "./gradlew jettyRun" or via Eclipse "Run as server". The freedom of choice. "Run as server" is not hotreloading very good though.

Need to add gradle plugin to eclipse to use this or run:

"./gradlew eclipse"
Instead of supporting different installations of web at the same server where you distinguish between each and one of them by creating different log settings etc. Use Docker instead. And isolate each instance.
