[PATCH] Adding custom manifest directives to jar file

Here is a patch that allows use of user-supplied manifest file.

This user-supplied manifest file will be merged with Maven-supplied properties (Created-By, version properties etc.) and included in JAR-file. If there is no user-supplied manifest file the behaviour is the same as now - just Maven-generated properties will be in manifest file included in JAR-file. User may set property maven.jar.manifest to specify path to manifest file. Default is $

{basedir}/Manifest.mf (or may be ${basedir}

/src/Manifest.mf is better?)

The patch created again maven-1.0-beta-6 distribution.
