[2.0.21] buttons for changing research priority should return, icon should have drag functionality

[PSYCHOELECTRIC]

2.0.21 adds dragging as a feature to change research priority, and i 100% agree that dragging should be an option. however, with this change, the manual buttons have been removed. both from an accessibility and new-player standpoint, the buttons are good to have if its not obvious what the new bars symbol is meant to represent.

my proposal is to simply add the buttons back, but give the drag functionality only on the icon itself. best of both worlds.

The icon itself is already draggable. The "bars" thing isn't an icon - it visually looks like a ribbed surface, which is grippy.

im aware its on the icon, i worded it weirdly. i only meant to just add the buttons back. i just called it an icon because i couldnt remember the word ribbed, for some reason lol
