Title: Quick bug fix and some repo improvements

I tried to run a simple query against the Xively API and got the following error:

```
❯ irb 1.9.3-p392
irb(main):001:0> require "xively-rb"

irb(main):002:0> client = Xively::Client.new("ommitted")

```
I have added a `require` for the version file in `xively-rb.rb` to fix this.

I've also:

- Renamed the `.rbenv-version` file to `.ruby-version` and remove the `ruby` prefix to stop rbenv giving me warnings (this is on 0.4.0 of rbenv).
- Added some badges for the repo
- Added license to gemspec to stop `bundler build gem` from giving me warnings.
