Keep info about active tab item

[ashbaldry]

Similar to Appsilon/semantic.dashboard#93, it would be good to be able to reference the active item in tabset() within the server function, much like tabsetPanel() in standard shiny.

@ashbaldry True. We'll increase the priority of that, however, of course, PRs are welcome :)

@dokato I have got part of it working, it takes the tab-name on every time the tab changes except on the initialisation of the shiny app. I've tried onFirstLoad but didn't seem to work. Change is available here

Hi @ashbaldry
The feature was added in #132
Thank you for contributing. Your code required a few changes, please check the PR to find out the correct solution.

Ah, thanks @krystian8207, much neater! Will remember the initialisation bit for the future :)
