switch help framework to 'authorS', remove all author[]

[commy2]

• changes CBA Help framework to use new BI author entry. (while filtering out all BI classes)
• to keep functionality of having multiple authors per PBO, add optional authors[] entry.
• add standardized STR_CBA_Author string as author to all CBA PBOs.

This will not fix the No Entry blah/author error pop ups of other mods. Either BI fixes the game or every mod author has to adjust.

Example:

        author = "$STR_CBA_Author";
        authors[] = {"Solus","Killswitch","commy2"};

will be displayed as: CBA-Team, Solus, Killswitch, commy2

2 spaces indentation?

Same as other .xml files.

CBA Team (two words, no hyphen)

I will also change authorURL to prioritize the new url entry
