[Orgmode] BUG sorting function

[Fritjof]

I think i found a bug. The sorting function dosn't seem to tell the  
difference between '*bold*' and '* heading' at the beginning of a line,  
and when a heading have *bold* tekst at the beginning of a line, trying to  
sort will give this error: "Region to sort contains a level above the the  
first entry"

Reproduce with:

* heading
** subheading
*not a heading*
some texkt

----
Also second level headings can't be bold, they show up as normal text.

Reproduce with:

* heading
** *subheading*
