Summary:
Swift doc comments on methods have an inconsistent styling and they don't seem to support all the previous key terms such as `discussion` and `abstract`.

For example, for what was `:return:` it is `- returns: ` but for what was `:param:` it is now `- parameter ` without the `:`

Steps to Reproduce:
1. Use Xcode 6 and create a Swift 1.2 project/file
2. write a method
3. Document said method with key terms for parameters, warnings, return type, etc
4. Open Xcode 7 and migrate the project to Swift 2.0

Expected Results:
I would expect formatting to be consistent between the key word types & that the migrator would migrate all previous key words correctly & all previous keywords would be supported

Actual Results:
`discussion`, `abstract` `warning`, `note` will not migrate. Formatting style between key words is not 100% the same for all & not all previous key words are supported

Version:
Xcode Version 7.0 beta (7A120f)

Notes:


Configuration:
Xcode 7 & Swift 2.0 project
