Document GIT_STRATEGY=none

## What does this MR do?

Adds documentation for the new `GIT_STRATEGY=none` option in GitLab Runner v1.7

Speling and grammar, of course.

I'm using the term 'project workspace' to refer to the build directory, which is a Jenkins-ism. Is there preferred alternative wording?

Prevent flash alert text from being obscured when container is fluid

## What does this MR do?

Fixes [a regression](https://gitlab.com/gitlab-org/gitlab-ce/commit/a2af7790) that causes the text within server-initiated flash *alerts* (not flash *notices*) to be obscured when `.container-fluid` is applied. It was reported in relation to a cherry-picking flash alert, but the problem occurs with all server-initiated flash alerts contained by a fluid container. 

## Are there points in the code the reviewer needs to double check?

Note that as part of this fix, I combined some duplicate code and removed `.flash-text` & `.content-wrapper` selectors as they didn't seem to be necessary.
 
I manually tested JS-initiated Flash alerts to make sure this doesn't affect their appearance. I also grepped around for anything else that might depend on these styles. Everything checked out. But... can *you* see something this is going to break?

## Why was this MR needed?

Affected users can't read flash alerts.

## Screenshots (if relevant)
