Added in extern global variables and printing of *char and string to stderr with printlnerr, printerr. Note that this will still compile in a previous version, but instead of extern, stderr will be newly declared. This is ok, because this version of the compiler never uses it, so we'll only use it after this one is bootstrapped in.
