This patch strip out dependency on Russian, as its complicated relationship
between spelling and pronunciation overburden rules for Belarusian. The rules
themselves are also added. They don't have devoicing at the end of the words
for now. Also, gemination of consonants doesn't work as expected, as it seems
on the top of this rule some other rules apply. This after-processing is
responsible also for the strange behaviour of ending [a].

This removes these words from dictionary and uses translation rules
instead. Result is to shorten the i.

cmn (Mandarin chinese) has been broken since 4825905.

This fix makes mandarin behave more like Cantonese. Instead of
translating characters, we search for dictionary matches.

The functionality of normal vs Chao tones should be investigated more.
Looks like latin characters as pinyin still uses Chao tones whereas
the characters in cmn_list and cmn_listx do not.

See #1044 for discussion. See also #1028 and #1163.

I added some number for Hebrew because is missing probably
