  -----------
  Make del a regular statement rather than only a top-level operation

Now that del generates code to delete stuff at runtime, it needs to be
a regular statement that can be included in functions rather than only
operating at the top level

  Log Message:
  -----------
  Don't cascade error messages

Once snek_abort is set, stop printing more messages as those are likely
a consequence of the first.

  Log Message:
  -----------
  Use \n for newline in error text

Syntax errors often occur at new line as a result of incorrect
indentation. Instead of printing \x0a, print \n which should be easier
to understand.

  Log Message:
  -----------
  Switch string literals from octal to hex for arbitrary char notation

If we only offer one string literal notation for arbitrary characters,
let's make that hex instead of octal. Python's hex syntax is better
constrained too.
