Add full source for antlr project (version 3.4)
This replaces the existing source for an unknown version of the antlr-runtime
with the full source for the antlr tool. However, we are still building
just the runtime jar, not the full tool.
The full tool will be included as a prebuilt jar, due to the complexities
of building this tool.
Since we will have both the full tool and the runtime jar in the Android tree,
the module name for the runtime jar has been changed from "antlr" to
"antlr-runtime"
