ghc-memory-0.13-6.15

- update 0.11

- update to 0.10
  * make memConstEqual more constant not using boolean comparaison
  * memConstEqual was comparing length times the first byte instead of comparing
    all the bytes one to one
  * Add Base64 variants

- update to 0.7
  * Fix fixed sized scrubber written too hastily, that would zero out memory, as
    the index was written through byte size, whereas the primitive would consider it
    as WordX type index. it would helps if Ghc.Prim had better documentation.

- initial commit
