How install Qt 5.7.0 released on Ubuntu

Qt Core Module

•     Added qAsConst function to help using non-const Qt containers in C++11 range for loops.

•     Added support for converting a floating point to its shortest and exact string form, without having to pre-calculate the number of digits.
•     Improved C++11 support by using std::atomic as backend for QAtomic classes and adding QTypeInfo for char16_t and char32_t.
•     Added QIODevice support for multi-streaming.
