OpenTaiko Pre v0.5.3

/!\ This release contains the same application as the 10th January one, but adds a default skin and default (empty) song folders, some of it's bugs are already patched, please clone latest commit and build double clicking on build.bat it you want to do bug hunting (I will be very glad if possible)
Since some of the default skin assets are no longer mandatory on the latest commit, placeholders assets were added for some textures, so irregular visuals can occur in certain cases.
