Group Confirmed: and NoRepro: tags; Add color/flag to special tags

This commit groups all of the Confirmed:(version):(OS) and
NoRepro:(version):(OS) tags into two separate tag bins, "Confirmed
[grouped]" and "NoRepro [grouped]". It also adds some nice orange
color to any tag that is grouped like this.

Any 'ignored' tag (currently just "BSA") is also flagged/renamed as
"BSA [ignored]".
