[#2305] Make it possible to disable the REPL type auto-detection

 * Add new defcustom `cider-switch-to-repl-after-insert-p`: Set to prevent cursor from going to the repl when inserting a form in the repl with the insert-to-repl commands.
 * Inject piggieback automatically on `cider-jack-in-clojurescript`.
 * Introduce a new command named `cider` (`C-c M-x`) that acts as a simple wrapper around all commands for starting/connecting to REPLs.
