Check archive for potential "Duplicate file" problems before processing

[GoogleCodeExporter]

When creating "zip" or "war" archive an exception can be thrown when there are 
duplicates.
See issue #84 (http://code.google.com/p/maven-play-plugin/issues/detail?id=84) 
as an example of this problem.

As a result there can be:
- ".zip" or ".war" file with partial content in it (for "zip", "dist" and "war" 
mojos),
- "target/dist" or "target/war" directory with partial content ("dist-exploded" 
and "war-exploded" mojos).

The archiver must be checked for potential problems before the actual 
processing.
