* bump ua-parser to 0.9.0

* fix unit test

* fix unit test

* fix travis

* add support for py34

Is better to calculate and provide a method to calculate the string values for `device`, `os` and `browser`  instead of doing it  directly on `__str__` method. 

This way the users may use those methods to get each data directly. Instead of having to make a `user_agent.__str__().split('/')` to get each value

The duplicate line show a bit of useless.

* Don't mark tablet using mobile browser as mobile

There are cases (e.g. iPad using Chrome mobile) where a device ends up
being marked as both tablet and mobile.

The commit gives priority to explicit device family over determining it
from browser family.

selwin#107

* Mark Kindle as a touch capable tablet...

...even when requesting a desktop version of page.

See:
https://docs.aws.amazon.com/silk/latest/developerguide/user-agent.html

selwin#107

* Ensure devices marked as tablets are not marked mobile as well due to their OS

* Ensure PC not marked as mobile due to browser family

* Ensure iPad is recognised as touch capable

Irrespective of the browser it is running

* Mark generic android tablets as tablets only

and not PCs

* Ensure Generic Smartphone is marked as touch capable mobile device

This is a very minor thing, but this will prevent 3x branches, and make the code slightly cleaner :)
