Add help() function to Lua "builtins."
help() with no argument lists all our viewer builtins. help(function, function, ...) shows help text for each named function. Each argument can be either a string or the function in question (e.g. help(help)). To support Lua-related text containing line breaks, make LLTextEditor:: pasteTextWithLinebreaks() a public template method. Change the existing implementation, which specifically accepts (const LLWString&), into its LLWString specialization. The generic template passes llconvert(arg) to that specialization, the one real implementation. Make LLFloaterLUADebug methods call pasteTextWithLinebreaks() instead of insertText(), which ignores newline characters. To allow help() to accept an actual function as well as a string name, add a lookup-by-function-pointer map to LuaFunction. (A Lua function does not store a name.) Make the constructor store an entry in the new lookup map as well as in the original registry map. Change LuaFunction::getRegistry() and getRegistered() to getState() and getRState(), respectively. Each returns a std::pair, but the first binds non-const references while the second binds const references.
