(DONT MERGE ME) I'm trying to ignore MANIFEST.MF, and I'm stuck

Since Issue #35 (Provide option to keep original plugin.xml and MANIFEST.MF) is getting some attention this weekend, I figured I'd bring some attention to the opposite issue, to ignore the original MANIFEST.MF for a pure-wuff solution.

The code for OsgiBundleConfigurer.groovy works - if ignoreManifest is true, then Wuff will not parse the exisitng MANIFEST.MF.

The code for Config.groovy is broken.  It seems simple, but when I set `ignoreManifest = true` in my build.gradle, it doesn't get set inside Wuff.  So, I have set the default value to true (which I want, but probably not other users) and I'm punting the issue up to you ;-).


Seems like it would be great to have flags and defaults such as:
readManifest = true
writeManifest = true
overwriteOriginalManifest = false

Which I believe is the current behavior, but would allow for the various custom use-cases people are asking for.
