Always update outputTimestamp

[qoomon]

Current Behaviour
outputTimestamp value is only updated if versions:set has changed version value

Expected Behaviour
outputTimestamp value should be updated always if versions:set is executed or at least for -SNAPSHOT versions.

Maybe new parameters with values:

• never
• always
• onchange

For SNAPSHOT I don't see benefit - in standard way project is always in snapshot version

[qoomon]

A parameter would be awesome, however what's the disadvantage in always setting outputTimestamp?

[slawekjaranowski]

In standard situation when nothing is changed also outputTimestamp should not be changed.
So my proposition is to add flags to preserve current behavior.

[qoomon]

sound reasonable
