Item12933: Make filtered characters configurable in JQueryWikiWord

Sometimes it would be helpful if one could allow additional characters for jqWikiWord, for example a "-" with TopicTranslationPlugin.

Proposed patch:

This is a very useful feature.

However I reverted the logic a bit: instead of specifying the forbidden characters it requires to list those that are acceptable in a wiki word. So instead of writing

forbidden: '[^a-zA-Z\\d]'

you'd now write

allow:'a-zA-Z\\d'

This change is required as the same character class is used to (a) gather good substrings that are then capitalized each before concatenating them and (b) filter out all bad substrings from the result. Your patch only did the latter, so capitalization won't happen on the correct boundaries.

Btw in how far is this feature related to TopicTranslationsPlugin?

Cool, thanks.

Regarding TopicTranslationsPlugin: You need a suffix for different languages and you probably want it to contain a disallowed char, like this: "MyTopic-EN". An issue comes up when you use wikiword plugin for the rename dialog.
