[O] ox-latex: default packages cleaning

[Rasmus]

Hi,

We could do some cleaning of org-default-package-alist before Org 8.3.

* tolerance

Why is "\\tolerance=1000" part of org-default-package-alist?  Is this
value good for all languages?  If we keep it, it should be configurable.
But people who explicitly wants this behavior can probably add it
themselves.

If it's a means to archive "high-quality" paragraphs, maybe microtype is
probably the 'proper' fix...

* Fixltx2e

This packages is depreciated with TL2015 cf. LaTeX News 22.  We can use
\RequirePackage[current]{latexrelease} but there's no point in that....
AFAIK latexrelease only useful for backwards compatibility.

* marvosym¹ 

This is used for

     ("EUR" "\\EUR{}" nil "€" "EUR" "EUR" "€")
     ("EURdig" "\\EURdig{}" nil "€" "EUR" "EUR" "€")
     ("EURhv" "\\EURhv{}" nil "€" "EUR" "EUR" "€")
     ("EURcr" "\\EURcr{}" nil "€" "EUR" "EUR" "€")
     ("EURtm" "\\EURtm{}" nil "€" "EUR" "EUR" "€")

We could either call \\texteuro{} or use eurosym.  IMO, if people wants
something more sophisticated than \texteuro (which depends on the current
font) can load marvosym or eurosym.

* Wasysym² 

Wasysym is used for a couple of smileys.

     ("smiley" "\\smiley{}" nil "☺" ":-)" ":-)" "☺")
     ("blacksmile" "\\blacksmiley{}" nil "☻" ":-)" ":-)" "☻")
     ("sad" "\\frownie{}" nil "☹" ":-(" ":-(" "☹")

I don't know why these smileys are blessed when '😱' and '😺' are not.
Ideally, you'd just use unicode smileys, but this requires {xe,lua}tex.
So for now we can could use \(\ddot\smile\) and \(\ddot\frown\) and shave
off the extra dependency.  Put perhaps it's better to just let people
choose themselves which smiley command they will want to use in which case
we could also just remove wasysym.
