Merge development (#39)

* add DropAllIndexes() method (#25)

Create a new method to drop all the indexes of a collection
in a single call

* readme: credit @feliixx for #25 (#26)

* send metadata during handshake (#28)

fix [#484](https://github.com/go-mgo/mgo/issues/484)

Annotate connections with metadata provided by the
connecting client.

informations send:

{
 "aplication": {         // optional
   "name": "myAppName"
 }
 "driver": {
    "name": "mgo",
    "version": "v2"
  },
  "os": {
    "type": runtime.GOOS,
    "architecture": runtime.GOARCH
  }
}

to set "application.name", add `appname` param in options
of string connection URI,
for example : "mongodb://localhost:27017?appname=myAppName"

* Update README to add appName (#32)

* docs: elaborate on what appName does

* readme: add appName to changes

* add method CreateView() (#33)

Fix #30.

Thanks to @feliixx for the time and effort.

* readme: credit @feliixx in the README (#36)

* Don't panic on indexed int64 fields (#23)

* Stop all db instances after tests (go-mgo#462)

If all tests pass, the builds for mongo earlier than 2.6 are still failing.
Running a clean up fixes the issue.

* fixing int64 type failing when getting indexes and trying to type them

* requested changes relating to case statement and panic

* Update README.md to credit @mapete94.

* tests: ensure indexed int64 fields do not cause a panic in Indexes()

See:
* #23
* https://github.com/go-mgo/mgo/issues/475
* go-mgo#476

* Add collation option to collection.Create() (#37)

- Allow specifying the default collation for the collection when creating it.
- Add some documentation to query.Collation() method.

fix #29

* Test against MongoDB 3.4.x (#35)

* test against MongoDB 3.4.x

* tests: use listIndexes to assert index state for 3.4+

* make test pass against v3.4.x

  - skip `TestViewWithCollation` because of SERVER-31049,
    cf: https://jira.mongodb.org/browse/SERVER-31049

  - add versionAtLeast() method in init.js script to better
    detect server version

fixes #31
