Allow renaming of root directories

I just installed the Seafile Drive Cient 2.0.6 on Ubuntu 18.04. The drive is mounted in the home directory ~/SeaDrive and the client works like a charm :slight_smile:

├── My Libraries
├── Shared with all
├── Shared with groups
└── Shared with me

The root folders, however, cannot be renamed. They contain space, which gives me an uneasy feeling when working with my files via the terminal. Most modern shells handle spaces quite well, but if I want to utilize legacy scripts for handling, for example, backups, spaces in the directory names can become very problematic.

Please consider implementing the possibility for the user to change the folder names to increase the compatibility for unix systems.
