Texturize 1.1

Since the original release of the framework, I've took some time to update 3rd party dependencies and simplify the build process. No new features have been added, but since this update now uses OpenCV 4.0, backwards compatibility has been broken. This update prepares the project for further development.

Changelog:

• Updated from OpenCV 3.3.1 to 4.0.0
• Rewritten file storage and persistence library
• Simplified the build process
• With this version, in-source builds are no longer supported
• Minor bug fixes
