Remove packaging files

They will be developed in their own branch from now on.
chmod a-x btsync-makeconfig.sh
Change default storage_path to ~/.btsync

Since these files are application data rather than configuration.
Change default WebGUI port to 7889+$UID

Instead of constant 8888 for all users. This should mean that
auto-generated configs for different users should not attempt to use the
same port for the WebGUI.
Version 1.1.0

Changelog:
- Change default storage_path to ~/.btsync
- Change default WebGUI port to 7889+$UID
