Description of the issue

Running git status and git diff in large repos can take over 1-2 seconds each. By default, cmder runs both in series when generating the prompt text after every command.

So, running fast commands like cd .. in large repos can easily take 3-4 seconds for the prompt to come back.

Cmder already has a feature to disable the git status in the prompt to fix this by adding the following to your .git/config

[cmder]
    status = false

This is obviously faster, but I would really like to see the branch name still, and that doesn't require running either git status or git diff so doesn't slow down in large repos.

Proposal

Support an additional config option

[cmder]
    status = branchonly

Update get_git_status_setting to return true | false | 'branchonly', and in git_prompt_filter check for 'branchonly' before running get_git_status and get_git_conflict to decide on the color.

This change is backward compatible, and pretty small. I am happy to submit a PR to contribute this.
