remove Settings module

Better not to have this at all than to have a library that you can't
actually use in widgets/boot/settings code

-- Read/write app settings, stored in <appid>.json
-- Read/write global settings (stored in setting.json)
-
-Usage:
-```
-// read a single app setting
-value = require('Settings').get(appid, key, default);
-// omit key to read all app settings
-value = require('Settings').get(appid);
-// write a single app setting
-require('Settings').set(appid, key, value)
-// omit key and pass an object as values to overwrite all settings
-require('Settings').set(appid, values)
-
-// read Bangle settings by passing the Bangle object instead of an app name
-value = require('Settings').get(Bangle, key, default);
-// read all global settings
-values = require('Settings').get(Bangle);
-// write a global setting
-require('Settings').set(Bangle, key, value)
-```
-
-For example:
-```
-require('Settings').set('test', 'foo', 123);        // writes to 'test.json'
-require('Settings').set('test', 'bar', 456);        // updates 'test.json'
-// 'test.json' now contains  {baz:123,bam:456}
-baz = require('Settings').get('test', 'foo');       // baz = 123
-def = require('Settings').get('test', 'jkl', 789);  // def = 789
-all = require('Settings').get('test');              // all = {foo: 123, bar: 456}
-baz = require('Settings').get('test', 'baz');       // baz = undefined
-
-// read global setting
-vibrate = require('Settings').get(Bangle, 'vibrate', true);
-
-// Hint: if your app reads multiple settings, you can create a helper function:
-function s(key, def) { return require('Settings').get('myapp', key, def); }
-var foo = s('foo setting', 'default value'), bar = s('bar setting');
