Merge pull request #185 from authenticate/e99f34aaef9e070f2620f336447e0d6b284d9855

Minor Update for VS Files and .gitignore
Added VS2012 compilation instructions in the README.

Thanks to authenticate for all that!
Made the elemental passive effect be applied on attack and defense.

The effect is unfortunately hard coded for now, as I'd like to simplify
the way status effects are implemented first.
Fixed a Thanis battle animation while seeing it.
Fixed the status effects template image where an arrow was misplaced.
Simplified the status effect implementation.

I merged the status effects of the same types into one, and used
the full range of negative and positive intensity.

This permitted to simplify a lot of code and twisted logic in there
and permitted also to merge the element icons with the status ones.
Reverting VS project warning settings and .gitignore changes. This is a fork side only commit.
Adding a submodule for the VS2012 dependencies.
Added a UI theme option to the boot options menu.
Fixing all level 4 warnings and higher.  This is a fork side only commit.
