Note this technically won't build for now because of the lack of RoomMember support but I'll push that at the quotient-next branch next.
This is needed as well to get a branch that builds on dev.
Stop space hierarchy being duplicated. This is done by making sure old jobs are cleared at all resets and to make doubly sure when a child is inserted it overrides itself so there can never be duplicates
Add the ability to set and show suggested rooms for spaces.
This is just adding the basic functionality, we can do more things with it later like sort/filter the space home for example.
Add a space homepage with the ability to both create new room and add existing rooms to the space. This uses a tree model for the space hierarchy and will go to any number of levels. The user should only see the add options if they have appropriate permissions.
This MR also combines the create space and room pages and adds a lot of optional functionality for managing space children.
