Support windows in more packages

[trufae]

Right now r2pm.c supports windows. but only the packages containing R2PM_INSTALL_WINDOWS() directives do work in there. the packages must be updated to ship an installation script, ideally using binary builds of the packages to get them installed in the right place. powershell is probably prefered over cmd scripts.
