Add JNAerator config file for Linux
Fix the glib Linux JNAerator config to produce compilable output

JNAerator needs a library name that matches the actual shared library
after applying the naming convention specific to the platform. For
glib, it is glib-2.0, but the dot confuses JNAerator default package
name generation, so an explicit package name is also required.

Some include directories were also missing. This commit adds them.
Add bridj jar

JNAerator produces output that needs bridj to work by default.
Resolve this dependency by including the jar for now.
Add a quick and dirty Ant build.xml
Update the readme
