What happens if only unprefixed EME is available?

[shadi, 2014/06/19 01:07:04]

It will only show the option of unprefixed EME. This still implies that
usePrefixedEME = false. 

Since this is confusing to read, I now disable the version (instead of not
showing it). The value of the option is a string used in test_config.js to
determine is usePrefixedEME is true.
