    Changes for Safe Haskell
    
    Ignore-this: c7c8f97541bd4ab2620613c51fad3b91
    
    Makes minimal necessary changes so that modules will infer as Safe
    for Safe Haskell.  Some modules are using rewrite rules, which are
    not Safe; to these I added Trustworthy pragmas.  The rewrite rules
    will continue to fire as normal, according to GHC's documentation.
    
    Other modules import Foreign.  I changed these to import
    Foreign.Safe instead.
    
    I changed the time.cabal file so that the minimum version of Base is
    4.4; that was the first version of Base that has the Foreign.Safe
    module.  (base 4.4 came with GHC 7.2, which is over two years old.)
