Add <finalName> tag to all poms that use war packaging

To aid in IDE/server integration (especially IntelliJ), it is extremely helpful if projects that generate wars create war artifacts named to match the intended target context names. Update poms with war packaging to include:

<build>
<finalName>.....</finalName>
...
</build>

I've tried this and it works well. However, not sure what other impacts if any this change will have in the larger build process.
