Settings: Issue Tracking Plugin description refers to "IBugTrackProvider2" (typo)
As can be seen in section 6.1.10. Issue Tracking of the documentation, the description of the Issue Tracker Plugin setting, in the Issue Tracking section, is:
Configures a COM IBugTraqProvider or IBugTrackProvider2 issue tracking plugin.
There is no such thing as "IBugTrackProvider2". Like the other version, "TraCK" is in fact spelled with a "q" ("IBugTraqProvider2"). By the way, it seems the "t" should be lowercase.
