Lock plist editor fields to vertical resizing

[chrisgrande]

Fixes issue #16 by disabling horizontal field resizing. Fields can still be vertically resized if needed.

On Safari I can still do this when resizing:

Notice how the first column has been squeezed out of existence.

Oops - I didn't apply the fix to the manifest editor just the pkginfo editor. New commit applies to both.

Still wonky:

Hmm, I can't reproduce it - are you just dragging the resize handle in the corner of the field? With those two commits it should only allow the fields in both editors to be resized vertically.

"are you just dragging the resize handle in the corner of the field?" yep. "With those two commits it should only allow the fields in both editors to be resized vertically." I'm still seeing some horizontal resizing.

Also: if you disable horizontal resizing -- what happens when the browser window is resized? It looks to me like the fields do not adapt their width...

[chrisgrande]

Very strange, I'm not seeing either issue. They resize on browser resize and don't budge if I try to resize them.

Thanks for this fix!
