Add spell checking support (issue #137). This includes: - Red underline of misspelled words in html text areas. - Right-click context menu options to correct the misspelled word. - New CefBrowser::ReplaceMisspelling method for accepting a word replacement. - Methods added to CefContextMenuParams for retrieving spelling-related information. - Uses the unified text checker when auto-correct is not enabled to match Google Chrome behavior. - On Windows and Linux a hunspell dictionary file will be downloaded to the "<cache_path>/Dictionaries" directory as needed, or used from the <cache_path> directory if the file already exists there. The dictionary file will be downloaded from http://cache.pack.google.com/edgedl/chrome/dict/<LANG>-3-0.bdic where <LANG> is the language abbreviation. - On OS X the spell checking implementation will use the system NSSpellChecker implementation. The following command-line flags have been added: --disable-spell-checking => Disable spell-checking support (no red underline, no dictionary file download, etc). --enable-spelling-auto-correct => Automatically correct common misspellings while typing (like 'omre' to 'more' on Windows/Linux or 'ehlo' to 'helo' on OS X). --enable-spelling-service => Enable use of the remote Google spelling service (this requires Google API keys). --override-spell-check-lang=<LANG> => Use the specified dictionary language <LANG> instead of the language specified in the locales.pak file.
