Merged PR #637 - BTRFS support fix #93

+ BTRFS support
+ Refactoring of `disk.py` into `lib/disk/*.py`
+ `get_mount_info()` was reworked to support traverse backwards until mountpoint information is found (reverse-recursiveness)
+ `suggest_single_disk_layout()` was added/fixed to support BTRFS options
+ - `suggest_multi_disk_layout()` does not yet support BTRFS subvolumes in suggestive mode
+ `Installer()` now calls `create_subvolume()` and `mount_subvolume()` during loading of file structure on `mount_ordered_layout()`
