XSTS: Gamma compatibility regarding enum literals

[AdamZsofi]

The traces (.cex files) outputted by xsts-cli started to use the qualified names of enum literals.
This broke compatibility with Gamma, but as it turns out, inside Gamma, the qualified names are already the usual representation.

So the nice way to solve issues around this is:

• fix the parsing in Gamma to accept the qualified names (already done, I believe)
• but make qualified names consistent in Theta, i.e., we should accept the qualified names in the input XSTS as well.

Examples

Non-qualified:
main_Statemachine := S1;

Qualified:
main_Statemachine Main_statemachine.S0

You mean main_Statemachine := Main_statemachine.S0?
