yue-latn-jyutping assumes latin characters are jyutping.

cmn now handles all latin characters as English.

The old functionality of assuming latin characters are pinyin can be
achieved with new language cmn-Latn-pinyin.

This commit fixes cmn and yue.
CalcPitches_Tone() now accepts cmn for translator_name.
SelectTranslator() now has a case for yue instead of zhy.

This reverts commit 23a4d88f6b.

Breaks tests for cmn.

Option "language <name>"already causes SelectTranslator(<name>) to be
called. Having two options to do almost the same thing is unnecessary
and confusing.

In the long term, all options from SelectTranslator() should have a
switch case in LoadVoice() so they are user configurable (see #218). If
needed, a new option (maybe called "LoadOptions") could be added to load
an existing voice or language file.

Changes language configuration files for: hak, cmn, yue, ltg, ms, mb-ma1.
No changes to users.
