blaze.open() function renamed to blaze.from_*()
Mode in storage is respected in constructors now.  Fixes #83.
Default mode for storage reverted to 'a'ppend because tests expects that
Added some tests for r/w mode in arrays so as to avoid regressions
Merge branch 'storage-mode' of github.com:FrancescAlted/blaze into storage-mode
