Arch: ArchWindow.py fix alignment of library windows

[Roy-043]

Windows and doors from parts_library were not aligned with or inserted in a wall.

Additionally:
The existing code for presetdir never worked. I have solved this by treating presetdir the same as librarypath. So the same directory structure is expected in both paths. I think this makes the most sense.
