These are some improvements to the german voices, both default and mbrola. It fixes some sounds of phonemes and also pronunciation of words. I also modified the mbrola phoneme and voice files to make them sound more natural. The stressLength setting is that it matches the way espeak deals with the lengths.

Fixed my_rules file to make them compile

Formerly, q was pronounced exactly like k. This is not the case in finnish.

In general, most finnish exceptions should be inside rules since compound words and inflections are very common in finnish

This affects words familynames like Berglund and Bergholm and place names like Bergbackan.

This rule "CA) rg (_" only matches the place and family names, and exempts words like "org", in which the g should be pronounced.

In finnish these are almost exclusively swedish place names (Uleåborg) or family names (Lindberg)

Mostly these are related to computers and internet (usb, ict and facebook) but there's others as well.
