Default is none.
Add ADMIN_USERNAME to replace ALLOW_USERNAME

Set usernames of users with whom you want to share, without @, separated by commas.

User IDs & usernames both works now

While v1 supports either user ID or username, you may use both in v2.

Configurable option STORAGE is now a string seperated by commas(,).

e.g.:

# v1
STORAGE = ['Mega', 'GoogleDrive']

# v2
STORAGE = Mega,GoogleDrive

To use local storage, append Local to STORAGE, e.g.: STORAGE=Local,Mega

Instead of using TEMP_DIR, local storage now share STORAGE_DIR configuration with remote storage.
