AppDB: Escaping / new-line problems

[Francois Gouget]

A lot of AppDB entries have broken escaping and some even seem to have 
only one line. That greatly reduces their readability. Not sure if this 
is because the formatting was lost over the years. Hopefully it can be 
fixed in one go for all entries. Otherwise we'll have a big AppDB 
janitorial cleanup task...

Here are some examples:

* Gepasi

    Lots of backslashes, quotes are escaped. Appears to be all on one 
line.

* StreetChaves
    http://appdb.winehq.org/appview.php?appId=1852
    Quotes and single-quotes are escaped. All on one line

* Neverwinter Nights
    http://appdb.winehq.org/appview.php?appId=870&versionId=1191
    Single-quotes are escaped.
