In JavaHL, add a variant of the ISVNClient.revert() method that
takes a set of paths to operate on, instead of just a single path.

[in subversion/bindings/javahl]

* src/org/apache/subversion/javahl/ISVNClient.java
  (ISVNClient.revert): Added an overload that accepts a set of paths.
* src/org/apache/subversion/javahl/SVNClient.java:
   Import java.util.Collections.
  (ISVNClient.revert): Make the native method accept a set of paths.
   Implement the single-path overload as a wrapper.

* native/SVNClient.h (SVNClient::revert): Accept an array of paths.
* native/SVNClient.cpp (SVNClient::revert): Same here.
* native/org_apache_subversion_javahl_SVNClient.cpp
  (Java_org_apache_subversion_javahl_SVNClient_revert): And here.
