Support FlexibleContexts #34
Description
Hi, I noticed I get lushtags: user error (Parse error: SrcLoc "MyFile.hs" 111 1: Malformed context: FlexibleContexts is not enabled) when I use the FlexibleContexts language pragma. This could probably be fixed just by recompiling, but it would be nice if the cabal file were changed as I don't think this change has any drawbacks.
