Bug 1453496 - [mozprofile] Bump version to 1.0.0 for Addon installation changes, r=gbrown

This is mainly to pick up bug 1448221 since the version of mozprofile on pypi can't
install addons with nightly anymore (due to the profile/extensions/staged directory
not being supported).

But since that change I've also landed several backwards incompatible API changes to
how addons are installed.

Bumping to 1.0.0 because I'd like us to start (attempting) to follow SemVer:
