[pve-devel] [PATCH-SERIES v3 manager] split up content view into a view for each type

[Fabian Ebner]

The goal of doing this is to have more flexibility/cleaner code for
content-type-dependent features in the content view. Now only buttons
that are useful for each content type are displayed. And it might make
sense to display different columns for different content types, e.g.
'parent' for cloned VM/CT images. (see #16)

API calls might be faster if only one type of content is requested.
The obvious drawback is that there is no view with all contents anymore.

The first patch is not directly related. It fixes the extension filters
when selecting a file to upload.

The last four patches are not directly related, but introduce grouping of backups
and introduce the prune window, which was essentially copied from the PBS code.

The prune window patch depends on this patch (otherwise it would error
out when all numberfields are cleared):

Changes from v2:
    * rebase on current master and deal with the new comment column
    * fix backup grouping for PBS storages
    * base prune window on the current prune window from PBS (there were
      some changes in the time since I sent v2)
