Provide a search / autocomplete / dropdown selection of valid system properties when configuring active effects and/or enchantments

Issue: For most people, they will not be familiar with the valid system properties (and any associated valid values) and will have to search the wiki each time they want to configure an active effect or enchantment. The wiki, while comprehensive, is neither convenient nor fast.

Solution: Add a search / autocomplete / dropdown selection of valid system properties when configuring active effects and/or enchantments. Also, where only certain values are permitted, also provide these as dropdowns. For module developers, also provide a way of a module registering any attribute keys it adds.

As a bonus, provide tooltips for each system property that describes its purpose (taken from the wiki).

Rationale: This makes it much easier to find the appropriate system property and makes it much more likely that users configure the effect or enchantment correctly. It also will reduce the number of queries in the Discord channel for help on finding the appropriate system property.

This would be such a huge improvement to setting up AEs without having to consult the wiki every time

I second this suggestion. It would be amazing to have something like this.

100% 3rd this- would speed up stuff like data entry and other homebrew creation stuff instead of needing to have another window open to reference the wiki. That and the wiki doesnt seem to always have "everything"
