Version 1.7.1

Features & Enhancements:

• Changed how the auto-completion API worked: it now allows asynch auto-completion! Have a look at how to set it up / update it](https://github.com/slackhq/SlackTextViewController#autocompletion)
• Added keyboard trackpad detection for iOS 9. Used internally for disables auto-completion while its detected, so we avoid crazy things! 👻
• Improved the magnifying glass detection.
• Gonna get a nice warning to remind you to super in viewDidLoad now. Fancy!
• Slowed down bouncy animation by 0.15 seconds
• Disabled cellLayoutMarginsFollowReadableWidth on iOS 9 for the auto-completion view. No need for large margins, come on!
