v0.5.0 Big files speedup and UI responsiveness upgrade

This release focuses primarily on improving large file support. Opening large files will now keep the UI responsive and the loading of a large file into the application is optimized to be much faster overall. Other features such as searching is also much improved for large files.

This release also includes new binary type "static". It includes all the Qt libraries inside the executable thus making the whole application just a single exe file. It still requires MSVC runtime installed on your system. The "non static" zip contains Qt libraries as the official dlls as built by Qt company.
