Rateamp 0.5.6.0b - New Release - 32/64bit

now I hope the plugin is compatible to 64bit systems.

The MS Platform SDK say the used one are the right functions to "...write code that is compatible with both 32-bit and 64-bit versions of Microsoft® Windows®..." I hope this will do so.

Additional there are a minor change: If you move files an empty directory will now be deleted.
