Filepaths that are longer than 255 characters should be shortened

[breyten]

When using the directory method in the store part of the pipeline, errors will be thrown when memorious tries to save a file with a really long filepath (as seen above, in the image). This can be remedied by shortening the filename if such an error occurs.

@breyten Are you running in a windows/NTFS environment, or similar?
