Added llformat_to_utf8 Added LLProcessLauncher::getExecutable() LLStringTableEntry() ctor and dtor definitions moved from .h to .cpp (should be safe)
Added support for plugin debug messages and better error reporting when something goes wrong during start up of SLPlugin. Also added more debug output regarding general plugin messages as well as debug output related to AIFilePicker.
