Organize and contextualize extension store

[AMDphreak]

You need to re-establish trust in the extension marketplace. It's riddled with garbage.

1. The extensions discovery process needs to be fixed. Extensions need to be organized and presented contextually. How many extensions add one little thing to an existing extension, yet they receive the same visual weight in the extensions marketplace? This is trash design. Extensions need to be nested based on dependency, and grouped by whether they compete with each other. Two different markdown previewers that cannot be used simultaneously need to be shown as competitors, instead of showing up as items number 3 and 37 in a list of 100 extensions matching the phrase "markdown".
2. Quality extensions need to be prioritized in the results list as well. Anything that is trusted and tested by the developers of VSCode needs to be highlighted. For example, Microsoft's Live Server Preview plugin for HTML,CSS,JS works well because it's maintained. 95% of live preview extensions don't support CSS rules that contain JavaScript variables, so they are useless for testing any real web design.
