Refactor project files for consistency

[brylie]

Audit all project router.js files so they follow the same pattern:

• each router file is located in a component
• each component router file contains routes only for the component
• component router files are in the /component/client/lib/router.js file
• router onBefore or other hooks are either in core, or in the specific router file where they are used

Additionally, refactor the Settings component into several separate components. Based on discussion with @brylie and @frenchbread.

@jykae thanks for going beyond the definition of done here. As per our discussion, and approval from @bajiat, please refactor the settings component into separate components, with the following structure:

• /branding
  • /logo
• /settings
  • /client
    • /menu
• /proxies
• /users
  • /account
  • /profile

@frenchbread and @NNN, please be aware that @jykae will be moving these files around, so that you have as few conflicts as possible.

Also note, this should not affect the user interface. It is just a code-level refactor. We want to keep the great work on the settings page, including the navigation menu.
