Refactor converse-api.query and the RSM class

Browse Source 
- The `converse.api.query` method now no longer accepts an RSM instance.
- The RSM class now separates `query` parameters from `result` attributes
- Improve JSDoc docs and remove need to make `converse-rsm` a plugin
- Add typedefs for the options expected by RSM and `api.archive.query`

@ -33,6 +33,7 @@ Soon we'll deprecate the latter, so prepare now.
- #2201: added html to converse.env
- #2213: added CustomElement to converse.env
- #2220: fix rendering of emojis in case `use_system_emojis == false` (again).
- The `api.archive.query` method no longer accepts an RSM instance as argument.
- The plugin `converse-uniview` has been removed and its functionality merged into `converse-chatboxviews`
- Removed the mockups from the project. Recommended to use tests instead.
- The API method `api.settings.update` has been deprecated in favor of `api.settings.extend`.
