Added C3 syntax highlighting and LSP support.

Refactored TextUndoStack, now uses std::variant and avoids heap allocating each command.
Fix possible crash in Process::readAll.
Fix SyntaxDefinition::setSymbols.
Some minor improvements for Odin and Ü syntax definitions.
Fix Git plugin silent configuration.
