* Improve contributing guidelines for security

The 'above the fold' space is very important, it seems possibly wasted with screenshots which aren't legible without enlarging.

This is a proposal to move them down.

Fix incorrect tmpl in oauth when we have a custom authorize url. The tmpl will append an additional character "v" every time we save the settings.

* More detailed documentation on how to set up from binary
Also change recommended file locations

@ohwgiles points out that the config section should, in fact, still be in accordance with the "server" struct, which contains the "LFS" struct. I should just remove the line
```
sec = Cfg.Section("LFS")
```

Partial fix for #4088

* Partial fix for #4010

Swagger needs a description field in each swagger:operation response.  Adding
minimal text for now on the way to getting swagger validate to pass.  Many
standard swagger client libraries will not work with gitea until validate
passes, so prioritizing that over better descriptions for now.

* Partial fix for #4010

Swagger needs a comment line above each swagger:response comment -- it
uses these to populate the description: fields.  Adding minimal text
for now on the way to getting swagger validate to pass.  Many standard
swagger client libraries will not work at all with gitea until validate
passes, so prioritizing that over better descriptions for now.
