Use <%= x %> rather than ${x}

Grunt is messing with Lo-Dash templating and I'm tired of it. This works.

It's because all the configs is templated.
Release v0.0.5
Use %VERSION%

Another solution would be to get the config options raw, which would disable Grunt's temptlating for all grunt-bump config options. I think this is better.
Release v0.0.6
chore: disable travis as there's nothing to test now
