        Renamed a method/parameter for clarity and consistency, as well as some style
        cleanups and removing some ridiculously verbose log messages.
        Also added an _isEmpty method to the database and bridge for WebKit's use.
        Finally, added a central way for both WebKit and WebCore to get the icon database filename

        * bridge/mac/WebCoreIconDatabaseBridge.h:  Added _isEmpty and defaultDatabaseFilename
        * bridge/mac/WebCoreIconDatabaseBridge.mm:  Removed an unnecessary semicolon off most of these methods

        In addition to a few style/good-practice cleanups, this patch will convert the old icon database
        format to the WebCore format if the WebCore db is empty (implying this conversion has yet to take
        place).  After the conversion, it will delete all traces of the old format to free the unneeded space

        * Misc/WebIconDatabase.m:
        (-[WebIconDatabase init]):
        (-[WebIconDatabase _setIconURL:forURL:]):  Changed the bridge's name for this method to be more clear
        (-[WebIconDatabase _createFileDatabase]):
        (-[WebIconDatabase _iconDataForIconURL:]):  This grabs the raw data for use in the conversion function
        (-[WebIconDatabase _convertToWebCoreFormat]):  This does the actual conversion
