Turn off elegantTextHeight in quantum theme

Setting elegantTextHeight to true was a great experiment, but it led to
too much difficulty getting text to fit in space-constrained spaces
(action bar, list items). A long term solution is optical bounds, but
for the time being, just turn it off.

This patch fixes bug 14227056: "Language name displaying under Personal
dictionary are truncated in landscape mode"
