Add configuration property buttons.abbreviation.removeAcronymTab.
If set, the acronym tab of the abbreviation dialogue is not shown.
Properties noAbbr and noAcronym should only be used to determine whether the predefined abbreviations or predefined acronyms fieldsets should be shown as they indicate that such predefined items exist or not.
Property removeAcronymTab is missing to specify that the Acronym tab should not be shown.
As the acronym tag is deprecated, this is the only property really needed. It would not make much sense to remove the abbreviation tab.
