why did you remove this line?

[vsn4ik]

For unification banner for js and css files.

[acrobat]

ah yes I see, it's now in the usebanner task!

Thanks @vsn4ik for the cleanup! Can you restore these files:

• .npmignore (this was added in a pr for a specific case, so we should keep it for now (possible cleanup in 2.0)
• tests/assets/jquery-2.2.3.min.js (I've added this file yesterday to start some work on jquery 1 and 2 test suites)

Also please take a look at the travis build! Thanks!

@acrobat I'm not going to restore unwanted files and unused libraries.

Ok, I will add the new jquery file in a separate PR for extra tests. But the .npmignore file was added to fix #1742, so we should atleast keep it until 2.0 (then we can remove it and fix things an other way)
What you can do is move the content from the .npmignore to the gitignore file as npm uses that file if a npmignore is missing! (ref)

I see you did a lot of small changes to the main js file, the changes look good on first sight. Can you guys also take a look @hebbet @Azaret, thanks!

@vsn4ik thanks for fixing the comments! Is it maybe possible to move the changes to bootstrap-datepicker.js to a separate pull request. Other changes can stay in this PR and are ready for a merge!

[vsn4ik]

Done.

Thanks @vsn4ik! Will review the other PR soon!
