Started working on optional native key transformation module
Integrated native key transformation method into Cryptography class
Made build process of native module optional
Changed travis configuration so native library can be built
Added optional tests for native key transformation library
Fixed compatibility issues with Node.js v0.8.x
Accidentally forgot to update these parameters aswell
Ported native library to NAN, compiles now from Node.js v0.8.x - v0.11.x
Show build errors during native library compilation
Changed structure initialization to be a bit more compatible to various compilers. Should now work on Travis-CI
Updated README.md
Merge branch 'feature/native-key-transformation' into develop
