Support foo"bar" and foo{bar} function calling syntaxes

[Dan Sanderson]

Lua supports a special syntax for one-argument function calls whose values are strings or tables where you can omit the parentheses. Pico-8 counts this syntax as one token less than the equivalent with parens.

print"hi"    -- 2 tokens
print("hi")  -- 3 tokens

This is actually working, including matching token count. Not sure why I filed this. If I find the example I think was breaking I'll reopen.
