A patch from Leon for "slight patch to "other-field-size" of drop-down form element"" https://issues.apache.org/jira/browse/OFBIZ-5285

"other-field-size" of drop-down form element is a very nice feature, but it's crippled in current version.
attached a patch to make it works and added an example section for that into FormWidgetExample.

jleroux: Interesting, I did not know this feature existed, it was committed long ago by David (before ASF era)
