#66 Utf-8 aware, and better Chinese characters

[jiangx]

FreeMind 0.8.0's utf-8 support is limited, I think.
When open file, FreeMind simply loads file contents
into buffer without valid and proper encoding, if .mm
file version matches current freemind version.

All Chinese characters encoding as "&#x...;" is
meaningless for Chinese.

I have a patch for this:
