Enables right click, alt click, ctrl click for alt-click item window (#83179)

## About The Pull Request

This fix enables most of the clicks that have been disabled in the alt
click menu up to this point. However, I did have to cut out the pointing
thing it would do for right clicking. The only thing you aren't able to
do with the new alt-click menu at this point is dragging items onto each
other, pointing, and the shift-click context menu. Maybe we'll leave
that for another PR, because I think I'd have to rewrite core components
of TGUI for that?
## Why It's Good For The Game

Lets you perform almost all of the alternative and right click functions
on things you have alt-clicked the tiles for. I believe this outweighs
the benefits of pointing at stuff on a tile instead.
## Changelog

The alt-click item panel now lets you perform most of the alternative
click options.
