Console output should support alternative indentation #4

Currently all output produced with ConsoleAPI adds " " indentation in front of the start of every message and "| " infront of the part of the message after the line break:

  A really-really long line with lots of words in it, so long, in fact,
| that it cannot fit into a single line and has to be broken in two.

Acedia needs to support an alternative (chosen per-user), where there is not indentation at the start of the line, but instead an additional indentation after the line break.
