Is there a helper for relative time?

[juliusknorr]

@LemonAndroid I took the liberty to rebase the branch to current master. Tests run fine now, except for the failures.

It would be awesome if you could go though the commits and add a sign-off message, so that the CI is happy. 😉 I have written down some instructions on how to do that here: #512 (comment) You basically just need to change the HEAD~2 to match the proper base commit of the branch.

Is there a helper for relative time?

There are some angular filters for this:

deck/js/filters/dateFilters.js

Line 28 in 24f4f84

app.filter('relativeDateFilter', function() {

@juliushaertl Why do the travis tests pass but the dron tests do not?

Two more bugs to squash:

• Creating a card, adding labels to it, deleting it and restoring it => labels gone temporarily

Presumption is: How labels are rendered for existing and new labels is different.

• Deleteing a card with labels and reloading the page, then restoring it => labels are only shown when clicking on the card

@juliushaertl Should codacy not complain now, I consider this done now.

Great work @LemonAndroid Thank you very much for this enhancement.
