    lyx_pot.py: Fix regex for \Format
    
    Each token could be delimited by quotation marks or not. The previous
    regexes only considered this for two tokens and hence produced wrong
    matches for cases such as
    
    \Format gnuplot     "gp, gnuplot, plt"    "Gnuplot"     "" "" ""  "vector"      "text/plain"
    
    where the extension list wasn't parsed as a single token.
