libpebble2 doesn't install on python 3.5

[Yuri Pimenov]

Seems like enum34 is not compatible with 3.5.

% pip install libpebble2
Collecting libpebble2
Using cached libpebble2-0.0.8.tar.gz
Collecting enum34>=1.0.4 (from libpebble2)
Using cached enum34-1.0.4.tar.gz
Complete output from command python setup.py egg_info:
Traceback (most recent call last):

return cls.member_map[name]
KeyError: '_convert'

[Yuri Pimenov]

The library installs easily with enum34 commented out in setup.py.
