support non-numerical tags in version strings

[lanterndev]

If I give my package a version like 0.0.3-0, I'm fine, but if I use something like 0.0.3-dev, "jitsu deploy" tries to rewrite the version to "0.0.3-1" in package.json before deploying. Are non-numerical tags unsupported for some reason? They're valid according to semver.org.

i'm wondering if this is related #434 and jitsu's doing some weird version parsing
