js/loader: correctly get rid of data

I'm unsure whether this is a jQuery bug or not. The removeData()
function has no effect unless there is a matching data attribute.
Makes IMO no sense, as adding the attribute automagically adds data,
so why should removing it differ.
This patch makes sure that the corresponding attribute is removed too.

CSS/controls: fix margin
...
Problem was that as of CSS voodoo "padding" is not possible for our
"controls" section. Some control components therefore got margins,
but that's pretty ugly. This patch fixes this but pretends that all
components sitting directly below "controls" provide a root node.

forms: fix isSubmitted
...
Implementation made wrong assumptions. A form is submitted when the
submit button has been pressed. It's value is then filled, it also
is when you're just pressing "RETURN". RETURN triggers the FIRST
submit button in a form. This way we are also able to find out which
form button has been pressed.
Current implementation is still poor, however isSubmitted works as
expected right now - and so does autosubmission.

JS/loader: don't autorefresh while editing
...
We would loose our focus if autorefresh takes place. So we don't render
the new content in case a form field in the very same container carries
the focus. It would be great to have a better solution one far day, but
for now it plays fine like this.

js/history: do not remove special params
...
We used to do this to blacklist certain parameters to not trigger
heavvy actions twice when navigating through history. We also do
never want to see such parameters in our address bar.
This conflicts with our slightly more complicated new filter URLs,
unless we are able to handle them on client side this is disabled
for now. IMO it should be handled server-side and eventually invol-
ving one more redirect.

Ui/Sparklines: Remove img src before putting it into DOM

SVG chart was fetched although we removed image tags
from DOM. This happens when text is converted into
browser DOM model to use with javascript. Small

First step: get rid of the messy workaround for the problem that

JS: fix multiselect burning resources

Especially on browsers with slow JS like IE8 iterating again and again
over all rows used to harm response rendering. Immagine a dasboard with
a total of a few hundred rows refreshing every 10 seconds while taking
3 secs to render one dashlet... it's far better right now.
