This release fixes the following bugs:

- Fix: [Scrollbar used](https://github.com/wekan/wekan/issues/2056) [remote file from CDN](https://github.com/MaazAli/Meteor-Malihu-Custom-Scrollbar/blob/master/jquery.mCustomScrollbar.js#L50),
so forked package to https://github.com/wekan/wekan-scrollbar and included
non-minified file locally to Wekan, so that using scrollbar works without direct connection
to Internet. Wekan should not load any external files by default, as was case before
new scrollbar, and is again now [after this fix](https://github.com/wekan/wekan/commit/c546464d9f56117a8bf580512cd62fc1102559c3).

Thanks to GitHub user xet7 for contributions.
