I have made the following changes to the build file:

1) updated to use antlr v. 2.7.5H3
2) I have added to tools/etc/buildmagic/libraries.ent properties for all dependencies used by admin-console/build.xml
3) I removed the explicit path reference to these dependencies and then
and replaced it with a reference using the above mentioned properties

This has been done in preparation of porting the thirdparty build to head.

Please ensure you update the latest version of the libraries.ent file when you pick up these changes .
