Enhancement: Add local_git as framework

[DennisL68]

Is your feature request related to a problem? Please describe. The ´Front Matter` extension suits markdown files in plain git as well, but it has to many settings and views that confuses non-CMS users.

Describe the solution you'd like Add a framework that hides all features not needed when only working with git called local_git

When local_git is used hide the following: FRONT MATTER generic view

• GLOBAL SETTINGS: Local preview
• GLOBAL SETTINGS: Local server command

FRONT MATTER file view

• GLOBAL SETTINGS: Local preview
• GLOBAL SETTINGS: Local server command
• SEO STATUS: *
• ACTIONS: Optimize slug

FrontMatter Dashboard Se other request about git status. In the mean time

• Contents: Published
• Contents: In draft
• Contents: STATUS

When local_git is used disable the following: Accounts

• Sign in requested This option only supports GitHub accounts anyway

Function Front Matter: New article from template

• Slug conversion
• File name prefix

When local_git is used change the following:

• Relabel Front Matter: New article from template to Front Matter: New content from template This could be a generic change as well.

Describe alternatives you've considered The Contents tab could be reworked to display content of all available local git branches and the current git status of all files (requires a lot of work)
