Release of JCBR 0.5

Please find this version in the earlier post JCBR: Java Chinese Book Reader. In this version, the following changes are made.

• Support uPDB files made by mPDB 2.5.
• Remove the encoding menu. For big5 books, the encoding is Big5-HKSCS. For unicode books, the encoding is UTF-16LE.
• The preferences are saved in ~/Library/JCBR/preference.ini such that when the user uses a newer version, the same preferences are used.
• Add menu items for exporting and importing user preferences.
• Support PDB files made by mPDB 1.7. It seems that the PDB files made by mPDB 1.7 do not conform to the format described in the Haodoo website. Since the format created by mPDB 1.7 is not available, this support may not be full.
