Remove lib+.so from plugin's name

Fix #277.
Is this PR big and need to be broken down into smaller ones?

It doesn't look like you consistently remove the .so extension from the plugin filenames. Is there a reason for this?

No, it was just a mistake.
I searched for the .so and I found these two files:

• ./build/ignition-gazebo3/CMakeCache.txt:325 //Install .so files without execute permission.
• tutorials/physics.md:97 If that's a 3rd party engine, find where the .so file is installed and add

Should I remove those too?

I think that's fine because it's so repetitive

Should I remove those too?

No, those can stay

I think I shouldn't remove it from the custom plugins like libCustomEngine.so, libLiftDragPlugin.so, libSampleSystem.so?

Should I remove it from the ign-gazebo/test directory?

It can be removed from all of then, ign-plugin will be able to find them 😉

Should I remove it from the ign-gazebo/test directory?

That would be great, thanks!

I will work on it.

I didn't remove the extension name from the src/ and the test/integration
