handle special console commands with spaces in them

[mck1117]

rough steps:

• in cli_registry.h, add something like STRING_RAW to the action_type_e enum for "pass the whole arg string as one blob instead of parsing
• add a new function to use it near addConsoleActionS named something like addConsoleActionRaw
• call that from lua.cpp near addConsoleActionS("lua",....
• implement handling STRING_RAW in handleConsoleLineInternal. It will require some special casing for skipping argument parsing when it matches a STRING_RAW.
• add a test in test_util.cpp near testConsoleLogic
