Merges our hunspell change to hunspell 1.2.10.
This change refactors our hunspell change and merges it to hunspell 1.2.10. To compare with our old change to hunspell 1.2.8, this change changes the following points:
1. Use the original load_config() to parse the affix lines so we can use all hunspell options.
2. Enclose all our changes with '#ifdef HUNSPELL_CHROME_CLIENT' and '#endif'.
3. Remove unnecessary '#undef fclose'.
