[Doc] First system run

[M.Jessa]

Hi again.

More stuff after installation:
- The package manager is not translated or it does not honour language
settings.
- The same with the network and storage icons in kicker.
- There should be only one virtual desktop. 4 of them are just confusing
for "normal people".
- The documentation icons on the desktop are of no use for anyone but
advanced users. And they don't need those icons in the first place.

Besides that it looks pretty damn well :)


Cheers,
Marcin
