0.16.2

This release adds a new top-level function: default_client()
- This function can be used by users to get a default client that implements SlackWebRequestSender so they don't have to pull in reqwest and version match in order to send requests.
- Thanks to @bwasty for adding this in #42!

0.16.1

This release works around a Slack API bug causing deserialization issues
- Thanks to @dten for implementing the fix in #39!

0.16.0

This release contains several breaking changes
- hyper has been replaced with reqwest, but is still an optional dependency
- All response fields are now considered optional to prevent this library from breaking if Slack removes them
- All methods now take in a request object (e.g. PostMessageRequest) instead of each parameter separately
  - This allows better clarity when calling the API as it simulates named params
  - All request objects implement Default, so you can fill in the request with a ..PostMessageRequest::default() (or equivalent) to elide fields that are not being set
- All error types have been reworked to obtain better information from the Slack API about the issue
Support added for most other Slack APIs, including dnd, usergroups, mpim, and files.comments

0.15.0

hyper is now an optional (but default) feature that can be disabled to use a different HTTP client
- The only change this requires is in error handling. Error::Internal and Error::Http are gone, and Error::HttpRequest has been added. Error also no longer allows exhaustive checking to allow for future flexibility, though this limitation will be lifted before 1.0.
- See the pull request for more information
hyper dependency also bumped to version 0.9.4, if it's being used (thanks to @jgulotta)
Fixed several changes in the schema from the Slack API that would cause erroneous deserialization errors (thanks to @kiyoto)

Removed events module. Now returned to slack crate.
Add missing pub fields on some returned response objects
Fix api.test method to not require a token to call

0.13.1

Removed unused Error::Utf8
Removed Error::Url, panicing instead of returning an Err on url parse failures due to no user input used
