Move components page to pages section

[Kida]

Hi =)

I was already able to
- add the components link to the sidebar of the pages section
- show the pages sidebar on the components page instead of the theme sidebar

But I can't figure out, how to associated the components page with the pages section in terms of tab navigation (it still highlights "theme" here) and, more importantly, permissions.

I need this to work, because some users are not allowed to use the themes section, but should be able to edit components.

Help would really be appreciated!

Best,
Kida
