• More correct "return value" for things like use statements.
• Initialize tab completion later, so that added commands get completion (Thanks @damiankloip!)
• Add a CodeCleaner pass to make exit; act like the exit command (Thanks @damiankloip!)
• Don't assume the presence of argv in $_SERVER.
• Add color mode overrides, via colorMode configuration and --color or --no-color flags (Thanks @toddmazierski!)
• Add a useUnicode config option. Set this to false to avoid non-ascii characters in PsySH output, for example if you're on Windows and don't want to fight with code page configuration.
• Update README, documentation, etc (Thanks @dereckson and @ReadmeCritic!)
