Reduce jQuery UI imports and use Bootstrap tooltips

[Hirse]

This PR has two changes that are not easily possible to split.

Currently, ungit is (unintentionally probably) using the jQuery UI tooltips instead of the bootstrap ones.

1. Only import the jQuery UI widgets that are used, i.e. autocomplete

   • Switch from jquery-ui-bundle to jquery-ui package
   • Add a new file that managest the jQuery UI import
   • Remove jQuery UI styles import as we use our own (see Style autocompletes like dropdowns #1327)
   • Replace jQuery UI styles import with only core styles, thanks for the hint @ylecuyer

2. Add custom styling to bootstrap tooltips

3. Fix placement of tooltips in button groups

I just replaced the jQuery UI package in the dependencies, but was wondering if it makes more sense to move it to devDependencies, since it is only used when building the bundle file.

@campersau What do you think?

When selecting a directory in the autocomplete a text gets displayed at the bottom.

There is also a general bug where tooltips are not initialized until a git directory is opened if you like to fix that too.

Not quite sure about moving jquery-ui to devDependencies yet.

It seems you need to include core.css and autocomplete.css (cf https://www.drupal.org/project/aloha/issues/1827626#comment-6672476) (https://github.com/jquery/jquery-ui/tree/c6f1735249295bb37153861aa97e5b3e38d46b02/themes/base) I tried and it works well

I was trying to avoid having to add any CSS from jQuery-UI.
I'll see if we can include (or copy) just the rules we need.
(Generally, I would not want to copy anything, but in this case we don't need to worry about future maintenance as jQuery-UI is not getting any updates.)

@campersau, fixed the issue as @ylecuyer suggested by adding the jQuery-UI core.css (back) to our CSS/Less.
