wip ui for search bar, no functionality

It seems there is a template for search boxes that could be reused:

• https://www.townlong-yak.com/framexml/live/Settings/Blizzard_SettingsPanel.xml#76
• https://www.townlong-yak.com/framexml/live/SharedUIPanelTemplates.xml#1483

I haven't looked into how it works exactly, but the search functionality itself should be doable as well.

As far as I can tell, the group table here could be filtered to remove all entries that don't match the given search term. Implementing a filter shouldn't be too difficult once the actual location in the code where it should be applied has been identified:

• For simplicity's sake, assume we're only filtering the (localized) item name
• Use Lua's string pattern matching capabilities to check if item.name is a match
• If not, remove the item from the table (only the GUI display group, not the actual database/saved variables of course)

Maybe that helps with the rest of this PR? :) Thanks for starting on this task.

It doesn't seem like there's anyone who currently has the bandwidth to design and implement this feature.

I'll close the PR until that changes. We can use the above as a starting point if/when the issue is revisited :)
