It is a server/client/guest issue.

Guest issue:
Checking the led state for modifiers does not always work (it doesn't work in vte in RHEL7) -> causes server to send "requests to sync modifiers" -> capslock is on for few seconds, then is off, then is on...

Server:
Server sends the "hw value" of the capslock key to the guest, but for example Japanese layout has "shift+capslock" to turn on capslock. So the server should send "shift + capslock" instead.

Client:
It just keeps syncing, it is not great if everything works ok. But maybe would be reasonable to stop trying to sync when it does not work.

I plan to implement some solution involving the agent (gdk can tell us the state of capslock, keycombo for its activation etc). But for some users may be reasonable to just disable syncing.

I added the checkbox to spicy just to test it. We have more options - a
configuration file, the settings file...
