v0.9.1

Improvements:

• MXRoomState: Improve algorithm to manage room members displaynames disambiguation.
• MXRoomSummary: Add isDirect and directUserId properties, thanks to @morozkin (#342).
• MXFileStore: New section with asynchronous API. asyncUsers and asyncRoomsSummaries methods are available, thanks to @morozkin (#342).

Bug fixes:

• Mentions do not work for names that start or end with a non-word character like '[', ']', '@'...).
• App crashed I don't know why, suspect memory issues / Crash in [MXRoomState copyWithZone:] (https://github.com/matrix-org/riot-ios-rageshakes#132).

API breaks:

• Replace [MXRoomState stateEventWithType:] by [MXRoomState stateEventsWithType:].
