This adds unified slash syntax for both sbt shell and the build.sbt DSL.
Instead of the current `<project-id>/config:intask::key`,
this adds `<project-id>/<config-ident>/intask/key` where <config-ident> is the Scala identifier notation for the configurations like `Compile` and `Test`.
This also adds a series of implicits called `SlashSyntax` that adds `/` operators to project refererences, configuration, and keys such that the same syntax works in build.sbt.
These examples work for both from the shell and in build.sbt.

The inspect command now outputs something that can be copy-pasted:
> inspect compile

This implements JSON-based port file. Thoughout the lifetime of the sbt server there will be `cwd / "project" / "target" / "active.json"`, which contains `url` field.
Using this `url` the potential client, such as IDEs can find out which port number to hit.
Ref #3508
Adds JVM flag `sbt.server.autostart` to enable/disable the automatic starting of sbt server with the sbt shell.
This also adds a new command `startServer` to manually start the server.
