API Improvements

[Crowfunder]

There are a couple inconsistencies within the API that should be relatively simple to fix.

Filtering ConfigEntry Responses

The API always returns full ConfigEntry. It would probably be optimal to return only the requested parts, especially since the default frontend display will be the routedParameters' field, and the expanded ownParametersorparameters` fields will be displayed only on-demand.

Inconsistent return types for PropertiesController

Some endpoints from PropertiesController return text/plain instead of text/json object. Which isn't very elegant.

More routedParameters

Some items, such as weapons, have more vital info that is kept in lists (First, #1 has to be resolved) or other types, it would be great to find a way to route them and parse, so that they are neatly displayed. (i.e costume colors, icon colors, attack colors, attack particles)
