feat: Make the default symbol (as in switch-case) more strictly detected

[XxX-Daniil-underscore-Zaikin-XxX]

JContainers is an excellent tool and a dependency for every mod and its dog. However, default is used as a parameter name in many JContainers functions - this means that any mod that uses JContainers cannot be compiled with the Caprica language extensions.

Aside from changing JContainers (and breaking any mod which depended on an older version), I think the best solution is to modify Caprica to only check for the default symbol when it's processing a switch-case.
