Fix display and translation of vocabulary values.
Compare the result of at_utils.translate call in these tests.

It is nice to know that the call does not raise an exception, but we
want a correct answer too.
Fix translating integer display lists.

Refs pull request #25.
Test that translating unicode values from vocabs goes right.

No longer use the unicodeEncode python skin script here, as the part we need is really simple.

Add changelog line for latest merges.

I have merged various vocabulary fixes, mostly for translations and IntDisplayLists.
The original changes were done in 1.9.x.
browser/utils.py and tests/test_browser_utils.py are now the same on 1.8.x and 1.9.x, so it seems good.
