[improvment] simplify "general settings" page

[htcfreek]

Summary of the new feature/enhancement

I think the general settings (startup, colour, update, ...) gets lost on the "general settings" page. You have to realize that they are at the end of the page and you must scroll down.
With every release we get more modules and the list of available modules gets longer and longer.

We should split the general settings page ore move the on/off switch to the related module settings page.

Proposed technical implementation details (optional)

Split the settings page

• page 1: general settings (startup, colour, updates, ...)
• page 2: available modules (name, description, on/off)

Move on/off switch

We move the on/off switch to the top of each module related settings page and don't provide an overview that list all the modules.
