Shift key issues on linux

[froymal]

It seems that the linux version of sneakysnek has some issues capturing keys that are pressed in conjunction with the shift key. So for example, when "A" is pressed it gets detected by sneakysnek, but "SHIFT+A" doesn't, this happens with non-alphabetic keys as well.

I looked around and modified the source code for linux_recorder by adding the ASCII mappings for the keys that aren't detected.

I have attached the patch file I wrote that fixes this issue. (Just change the extension to patch, GitHub doesn't accept .patch extension for some reason...)
linux_recorder.txt

Can confirm this issue occurs in the current version and is fixed by the patch.
