Add a refresh button

[Daniel Perovich]

The board refreshes when refreshing the page, which is slow.

Adding a refresh button that only resets the issues on the board to their current status, without refreshing the whole page, would be faster.

Dear Daniel,

The improvements suggested by you looks interesting. I've added it to my Team's backlog, so if anything changes you are to be informed about it.

Many thanks, Dominik
