Made Site.buildStatic() copy rather than symlink.
Symlinking did not work on Windows.
Static resource building made to work on Windows but still efficient on Unix.
Site.buildStatic() still symlinks to static resources on platforms that support it, but copies on those that don't.
Python does not support symlinking on Windows and native Windows method only works for admins.
Made buildStatic code comply with camelcase naming
