        Added some constants for SQL Result Codes to SQLDatabase.h
        This way, users of SQLDatabase can access all necessary SQLite functionality
        without having access to sqlite3.h.
        Also reordered some files in the xcodeproj and some #includes

        * WebCore.xcodeproj/project.pbxproj:  Reordered some files
        * loader/icon/IconDataCache.cpp:
        (WebCore::IconDataCache::writeToDatabase): Use our new result codes
        * loader/icon/IconDatabase.cpp:
        (WebCore::IconDatabase::sharedIconDatabase): Use our new result codes
        (WebCore::IconDatabase::retainIconForPageURL): Use our new result codes
        (WebCore::IconDatabase::pruneUnretainedIconsOnStartup): Use our new result codes
        (WebCore::IconDatabase::addIconForIconURLQuery): Use our new result codes
        (WebCore::IconDatabase::hasIconForIconURLQuery): Use our new result codes
        * loader/icon/SQLDatabase.cpp:
        (WebCore::SQLDatabase::lastError): Moved from header to eliminate dependency on sqlite3.h in header
        (WebCore::SQLDatabase::lastErrorMsg): Ditto
        * loader/icon/SQLDatabase.h: Removed #include <sqlite3.h>
        * loader/icon/SQLStatement.cpp: Added #include <sqlite3.h>
        * loader/icon/SQLStatement.h: Removed #include <sqlite3.h>
