Updated Client Cache & Download Links

[Nozemi]

Pitchblac32 has made adjustments to the game cache so the smithing interface should work properly now for the bars.

I also updated the download links to use the seamless launcher I made some time ago, hoping that it will work better.

*Edit* More adjustments have been added to the cache thanks to Pitchblac32. You will need to delete the old cache and download the new one manually to fix a few stuff:
- Prayer level now show up correctly.
- Relog should no longer remove bridges
