Enhancement: Implement result omissions feature that's available in everything 1.5

**Is your feature request related to a problem? Please describe.**

Currently the explorer plugins implementation of "Everything" doesn't adhere to how it's set up in the everything application. I suppose that's by design.

Result omissions are used to fine tune your search queries to only return files/folders that are of significance to what you expect to see. For example, I don't want any system files, caches or resource files to show up in my results. It can be on or off by default. It can also be dynamically controlled depending on your the default state by including "omit:" or "no-omit:" in your search query.

**Describe the solution you'd like**

Include an option to enable "Result Omissions" to be applied to the queries by default.

**Describe alternatives you've considered**

Allow the ability to modify that section to add custom filters or populate it by what's available in Everything. Not sure if Everythings 1.5 API allows it or not.

Doing either of that allows the user to tailor their default search results to the liking.
