Remove WebDAV redirect from the root path

introducing new dav property {xmlns:oc="http://owncloud.org/ns}id

Fix leftcontent/right content, fixes contacts app

- remove property only if present

Tasks app layout was broken since the controls bar is higher now.
This change should hopefully fix other apps using the same layout.

This will prevent people mounting the root path.
They should use the full webdav path instead.

Added jquery.placeholder shim to handle input field placeholders in IE8/9

The "show cruds" button is now embedded into the last label/checkbox
group and wraps with it.

Added ellipsis to prevent long names to exceed the dropdown's width.

Ignore duplicate inserts in file cache and mime type

This is to prevent conflicts with jquery libs that handle text
placeholders in IE8

The logo images are specified in the php templates with eg `image_path('', 'logo-wide.svg')`. If that file exists the correct path will be served to the client in the html template. Then the `SVGSupport()` is checked in https://github.com/owncloud/core/blob/master/core/js/js.js#L701 which will replace `svg` with `png` in img tags and css background definitions.

fixes #5074
partially solves #5421, but not when an svg has been specified in css and is then 'fixed' by js to point to a png which does not exist in the theme but is then might be resolved to an image from core .... well theoretical problem ... might not even be a problem

@karlitschek @jancborchardt please review

For certain file sizes, we rounded to the wrong chunk number
and the returned bogus results. This should fix
