Swift/1.2 - import ObjectiveC

[DanielAsher]

import ObjectiveC allows SwiftTask.swift to be included in the Sources folder of a playground.

my first pull request, so do let me know if anything is not quite right and I should resubmit.

Thanks, but why do you need import ObjectiveC?
It seems to work fine without it.

8.3 allows for a Source import mechanism that required the implicit dependency be made explicit. https://github.com/DanielAsher/SwiftTask-in-Playground-Sources-Folder demonstrates the issue, uncomment 'import ObjectiveC' to enable SwiftTask to build and load.

Thanks for providing a demo 👍
It looks like it's safer to declare import ObjectiveC explicitly just because SwiftTask uses objc_sync_enter/objc_sync_exit.

P.S.
This might also solve the issue in ReactKit/ReactKit#16 where ReactKit build failed due to error: use of unresolved identifier 'objc_sync_enter'.
