[pve-devel] [PATCH v2 manager 2/5] ui: refactor UploadToStorage.js

[Lorenz Stechauner <l.stechauner@proxmox.com>]

this also removes the "content" selector from the window.
as far as it seems, this selector was never able to select
more than one entry, so it was useless.

the check for FormData() is also removed, because this is
supported by all major browsers for a long time. therefore
doStandardSubmit() is also not necessary.
