Repeat-if statement chokes on quotes (multiline variables not parsed)

[smathot]

When you use quotes in a repeat-if statement of a repeat_cycle item, this results in a multiline variable, like so:

__condition__
[response] = "space"
__end__

This results in the following error:

I believe that this is a result of multiline variables not being parsed at all, thus resulting in a non-existent condition variable.

@dschreij I will push a fix for this soon, either as part of #19 if it's still open or as a new PR.
