gui: Move package to internal.

dcrpool is an application and thus all of its package not intended for
external consumers should not be publicly visible.

To that end, this moves the gui package to an internal package meaning
that it is no longer a part of the exported main module.

 ## Configuration
 
 dcrpool requires [dcrd](https://github.com/decred/dcrd) and [dcrwallet](https://github.com/decred/dcrwallet) when configured as a mining pool, it only requires dcrd when configured as a solo pool.
-Deploying the user interface requires copying the `dcrpool/gui/assets` folder from 
-source to a reachable location and updating the gui directory (`--guidir`) of 
-the configuration. Currently only single instance deployments are supported, 
-support for distributed deployments will be implemented in the future.
