Creating new files, folders or uploading files now have their sharing
icon updated accordingly.

For this, the global share status list that is cached in
OC.Share.statuses is reused for new files.

Performance should improve as the sharing list is now only loaded once
per navigation session.

In OC.Share, split loadIcons into loadIcons + updateIcons.

Fixes #4977

Fixes #5285

To make the status indicator appear smaller, even in IE8 that doesn't
support background-size, there is no a smaller animated gif
"loading-small" for that purpose.

- Fixed JS error that prevent the conflict dialog to open #5060
- Fixed JS error that prevented the overwrite case to run

Removed bold so it takes less space and set alignment to left.

 * Works in IE8, 9, 10, Firefox 24 and Chromium 30

When clicking on an autocomplete result in the sharing dropdown,
it will mistakenly be detected as being clicked outside and would
trigger the sharing dropdown closing.

This fix adds a check to detect clicks inside the autocomplete and
prevent closing the dropdown in that case.

This fixes #4142

Fixed the sharing notification checkbox label in the file sharing
dropdown, which makes it possible to click on the label directly.

When clicking on a link that points to "#" in the sharing dropdown, and
the current view is scrolled down, the browser will scroll the page up
to the top (anchor behavior).

This fix cancels the click event when clicking on "unshare" link or
"show crud" link.
