Packaging tasks do not check if package is already built

[wenslayer]

It appears that the package and packageMobile tasks do not declare their outputs, which means no up-to-date checks are run.

Repro:

• Run package or packageMobile on a project (that obviously provides suitable configuration).
• Confirm package artifact is produced in build directory.
• Re-run same task.

Expected Result:

• Gradle outputs UP-TO-DATE when attempting to perform the packaging task.

Actual Result:

• Gradle rebuilds the package artifact.

Ouch, this really hurts when using install* and uninstall* tasks, as they will always cause the package to be rebuilt, which can be 10's of minutes in our case. (Just in case you haven't seen this, @SlevinBE)

I've seen it, just haven't had the time to fix it ;)

Can this issue be closed now that #179 has been merged?

[SlevinBE]

You're right, it can :)
