CB-6976 Changes switch name from '--store' to '--win'
CB-6976 Reflect new switch name to project structure

For consistence reason.

1. Produce correct artefact names: Windows instead of Store
before: CordovaApp.Store_0.0.1.0_anycpu_debug
after: CordovaApp.Windows_0.0.1.0_anycpu_debug

2. Use <Windows> instead of <Store> suffix for file names to be consistent with terminology used in config.xml and command line switch and be more understanable for developers
