Change the set of characters in the "insert special character" dialog

[Martin Ørding-Thomsen]

Lots of html-entities exist, that are not shown in the list of characters. At the same time, lots of useless characters are shown, such as a-z and A-Z. Something needs to be changed.

Including a-z only makes sense if you make a truly complete list, including every unicode character, such as the one found in charmap.exe in Windows.

If you want to stick to an incomplete list, don't include a-z, as they are found on every keyboard anyway. And why not include all html-entities except whitespace? You can see them here, including their names: ​http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references

I made the change myself due to a customer request. I didn't include character descriptions.
