Add support for header files filtering

Now it's possible to specify include file mask(s) in addition to include
path (directory).

Example usage: source and header located together in the same folder.
Before this commit both source and header were copied into 'noarch'
artifact.

POM syntax before:
<includePaths>
  <includePath/>
</includePaths>

POM syntax after:
<includePaths>
  <includePath>
    <path/>
    <includes>
      <include/>
    </includes>
  </includePath>
</includePaths>
