Enable for all Atom scopes using ./ everywhere

Since I lost a couple of hours trying to short this out, I'm pasting my config.cson for future use by someone with the same needs...

```
...
"autocomplete-paths":
enableHtmlSupport: true
maxFileCount: 10000
normalizeSlashes: false
scopes: [
{
scopes: [
"source.c"

]
includeCurrentDirectory: false
prefixes: [
"\\.\\/"
]
projectRelativePath: false
relative: true
}
]
...
```

## PS

To get a list of all scope names registered in your Atom instance, open the Developer Tools Console and execute the following:

```
Object.keys(atom.grammars.grammarsByScopeName).sort().join('\n')
```

Ref: [file-types](https://atom.io/packages/file-types)

Start by reviewing the config.cson example, especially the scopes, prefixes, and relative settings, then use the Atom Developer Tools Console command shown to inspect registered scopes. Done means the ./ prefix behavior works across all Atom scopes without requiring the user to maintain a scope list.
