[Foldit] Fix how Linux reacts to the window close button.
Right now, the Foldit linux client is unceremoniously killed when you click the main (OS-generated) "window close" button. (Skipping any "save options" code, and often resulting in a segfault on exit.) The reason for this is that the "official" GLUT specification (apparently) does not have any mechanism for detecting this event and responding properly with cleanup. However, most Linuxes use OpenGLUT or FreeGLUT, which have an extension which is able to handle this (same API for both).
This PR adjusts the GLUTWrapper implementation to recognize when we're compiling with OpenGLUT/FreeGLUT, and use that mechanism. This requires a bit of a rework for the on_close functionality, because unlike the Windows or Mac equivalents, the program is getting closed when that box is triggered on Linux, with no mechanism to cancel it.
I also adjusted things such that the on_close functionality goes through the same handle_exit() mechanism the rest of the exit button in-game go through. The one exception is when the button is clicked prior to the login screen coming up, where handle_exit() causes crashes due to uninitialized variables, in which case we use the current approach. (You can still get crashes when closing prior to the login screen coming up due to multithreading issues, but those are crashes we already have in the released client.)
RELEASE NOTES: Fix how we handle the close window button for Linux clients.

[Foldit] Fix Collagen EduMode puzzle for disulfides.
Apparently you should be able to make disulfides in the Collagen puzzle. (Re)enable that.
RELEASE NOTES: Fix disulfide display in the Collagen Education Mode puzzle.

[Foldit] Bring panels to top and on screen when toggled.
Add `toggle_to_top()` functionality for panels which will bring the specific panel to the top (over other items) and will make sure the panel is on screen.
There's a slight rework of Widget::ensure_on_screen(), to make sure we don't cut off the top of panels (and thus remove the title bar handle) when the screen is too short.
RELEASE NOTES: Make sure panels are on-screen and visible when they appear.
Merge pull request #5765 from RosettaCommons/roccomoretti/interactive_hotkey_help
[Foldit] Update Help Panel.
This PR updates the Help panel for a few changes, but the primary one is to improve the way we display hotkeys. (Others are adding a Selection card, updating the Tweak image, and some other typo/formatting issues.)
RELEASE NOTES:
* Update Help Menu.
