Spaces are live!

Spaces are finally here. Create a new space and try it out! For now, you can only manually create directories and upload files one by one, but I hope to make batch uploads available soon.

Latest changes:

• Added a new file browser for spaces
• Added the ability to create spaces
• Changed lots of code and organized files better
• Introduced a lot of new permissions
• Fixed an API bug relating to space creation (Thanks Charlie)
