New features:
- Add function "j_reload_adddict()" to reload dictionaries.
- Add option "-lvscale factor" and func "j_adin_change_input_scaling_factor()"
to scale the amplitude of captured audio by the factor.
- Add option "-rejectlong msec" to reject too long input.
- Add minimum bayes risk decoding, contributed by H. Nanjo and R. Furutani
- Support binary N-gram symbol charset conversion by "mkbingram".

- Fix sending audio stream via network with incorrect byte order at
big-endian machines.
- Fix occasional failure of closing audio device at j_close_stream().
- Fix segfault when reading binary hmm created at 64bit env. with embedded parameters.
- Fix memory leak when failed to read an N-gram file.
- Fix memory leak when input length overflow is detected.
- Fix unable to load feature vector plugin.
- Update microphone input code for recent MacOSX.

- 辞書のリロード: j_reload_adddict()
