Sluift: Custom console/interpreter
- Prints results of each command (if it can be interpreted as an expression) - Stores results of last command in _1, _2, ... - Supports tab completion - Compatible with Lua 5.2 Other changes: - Add support for specifying custom editline library - Don't load sluift into global namespace. Tab completion should be convenient enough. Change-Id: I2a26346469d67c281d09d47cacaa0b267f5ea9f9
