Welcome Effects

Awesome graphic improvement today, I created a STR file loader and renderer. This file contain key animationsof some effects used in Ragnarok Online, so since #8cd630e0, roBrowser is now able to display some graphics effects.

I also wrote a viewer you can see below:

There is still some bugs as there are some part of the file I don't know how what they are used for, but it's a work in progress.

Note: Not all effects are rendered, only the one using STR file (and listed in the DB). There are a lot of effects in Ragnarok Online that are hardcoded and do not rely on files to be displayed.
