Changelog of @hackage/seqaid 0.3.0.0

0.2.1.1 -> 0.3.0.0

0.2.1.0 -> 0.2.1.1

added a non-manual USE_CPPHS flag to seqaid.cabal, which should in principle allow the client build system to try cpphs first, and if that build fails, then try again with a native cpp if there's one in the path (which is usually the case)
- this auto-toggle works for me with GHC 7.8.4 and Cabal 1.22.0.0
- what is the oldest version of cabal-install that this auto-toggling will happen in?...
improvements in platform-dependent handling in Demo.hs
and also in choice of leaky version in Demo.hs

0.2.0.0 -> 0.2.1.0

realised I should be using Manual: True in all my .cabal flags, or else the constraint solver is free to toggle them!!

** 0.1.7.0 -> 0.2.0.0
