Improve support for Reddit

[andreseg]

Improvements or customizations can be made to specific Apps or websites. Here is the location where those customizations exist: https://github.com/comake/yip-yip/tree/main/src/data/app_specific_settings

Below are a list of improvements that can be done for Reddit, similar to how Gmail has a customization there now.

• typing "home" or "reddit" should highlight the logo up top to go home

I think the rest of these icons up top should probably/also be prioritized. In other words, typing:

• "sea" should select search first
• "pop" should select popular first
• "all" should select all first
• "liv" should select reddit live
• "cha" should select chat
• "profile" and "settings" should select the dropdown in the top right of the screen
  maybe even "dropdown" should highlight the different dropdowns up top?

Typing:

• "up" should highlight upvote
• "do" should highlight downvote
