ffb9e883fa [fbreader] Don't require book language to be in languagePatterns.zip 
There ain't that many languages there, really. Not setting the language
may cause some format plugins to reset book encoding to "windows-1252".

1320c9d61d [fbreader] Feed expat with a random hash salt 
That's supposed to prevent DoS attacks based on predicting hash
function behavior (although it's hard to imagine that someone
would ever decide to attack the poor little Books app).

83ca0db6bb [fbreader] Improved handling of broken CSS input 
Particularly, curly brackets in inline CSS would make the parser crash.
Generally, it's better to stop parsing than crash when we get into an
unexpected state.

bd3dbb7d19 [fbreader] Fixed the problem with external XML entities 
XML parser's "hash_secret_salt" has to be set to anything non-zero.
Otherwise this parser won't be able to use the entity cache filled
by the child DTD parsers. For more details see CVE-2012-0876 and

noticeable amount of CPU time. For ASCII strings it's unnecessary.
