Hide Tag from navigation on the left in HTML report

[ahus1]

I want to tag my test cases with IDs from the ticket system so I can use the IDs as a cross-reference and search for them.

But the number of tickets would be too long on the navigation bar, therefore I would like to hide them from the navigation.

Implementation idea: maybe add hideFromNavigation to IsTag annotation?

I would like to have a positive setting, something like useForNavigation and set it to true by default.

I'd be happy to work on this after #172 (since this will affect the same area in the code).

[janschaefer]

I already started working on this :-)

[Airblader]

Then we'll have merge conflicts :-(

[janschaefer]

We will see, but I think we both have enough experience with merge conflicts ;-)

[Airblader]

Indeed, but I still prefer avoiding them. :-) We probably only have a conflict in ScenarioModelBuilder anyway. See #213.
