Emphasis and strong text lost when converting to ODT

[AmberHaelo]

This appears to be a problem with both 6.5.3 and 6.6.0, and is limited to ODT. The FODT output works as expected. To test:

$ multimarkdown -t odt -o test.odt
# Heading

> Block quote with *italic* text.

Regular paragraph with **bold** and *italic text*, along with the ***combination*** of the two.

The heading and quote will format correctly, but all italic and bold formatting is lost. As noted, the same exact test works fine for .fodt, by only changing the command line slightly.
