plugin: sorting, filtering, selection fixes

[takase1121]

This ended up a bit larger than I think, so I would love to have another pair of eyes looking at this before getting it merged.

1. You can now sort the table. Since the icon font is very limited, we don't even have proper icons to indicate the sort order. Currently I draw a line and I think this is less intuitive than it shold've been.
2. You can also filter the table. This is different than "find" as it doesn't rely on the small CommandView preview section, and is generally a better UX. I think binding this as CTRL+F makes more sense than the current find-plugin, but I would like some more opinion on this.
3. Arrow up and down now works correctly.

More things to discuss:

1. the sorting obviously isn't perfect. Version values aren't sorted correctly, and possible number values won't be sorted correctly as well since they're converted to a string.
2. Refreshing and filtering does clear the selection. I assume this is already an issue since the object reference changes, but if there's a need to keep that consistent we will have to do ID checks.

1. Yeah; the line isn't ideal, but it's better than nothing. I think it's good enough for now.
2. I agree it should be used over find. It's better. We should probably just nix find entirely. There should be some indication we're filtering (statusview?), though; and escape should clear the filter.
3. 👍
4. I think it's fine for now that version numbers aren't sorted correctly, but we should support this.
5. I think it's also OK to clear the selection; likely if you're filtering you don't really care about your selection anwyay.

I made ctrl+f use filter, and implemented escape to clear filter text, and preserves filter text on subsequent ctrl+f.

As for the filtered status, I personally don't like putting messages that should be long running on the StatusView. Sure it is for that purpose but people easily miss it (for example, the find next press F3 thing). I instead put it on the top of the table.
