Handle expandableTextboxes better for ant properties and ant_opts.

Specifically, the single liner of properties was previously turning into a single variable,
which isn't what was intended by the expandableTextboxes.

Additionally, having mutlilines for ant_opts caused java errors. These just needed
be to collapsed into space separated ant_opts

I just recently these and thought I'd take a shot at fixing them. Please review and let me know if you'd like to see the changes any differently.
