Fixing 'unity --reset'

[Jorge O. Castro]

Hi everyone,

Some changes to unity this cycle means that "unity --reset" doesn't
work. Didrocks sort of explained what needed to happen to make it work
and J Phani Mahesh stepped up to the plate taking a stab at it.

- https://bitbucket.org/jpmahesh/unity-reset/src/00e73b345dae/reset-gio.py?at=master

Some things here:

- It needs to be tested more widely.
- Someone needs to integrate it into Unity at some point once we know
it works so people can do "unity --reset".

Thanks J Phani for this contribution!
