Restored Web APIs to improve feature parity with QtWebKit 5.7:

• Indexed Database

This is completely new implementation, which doesn't depend on LevelDB anymore, and is more compliant to modern W3C standards

• Media Source Extensions (only when GStreamer is used)

This is still experimental, known issue is that some YouTube video with preroll advertisment are not playing, though it works fine in other cases. To enable it, use new attribute QWebSettings::MediaSourceEnabled.

• Device motion and orientation API
• Gamepad API (on Linux only)
• Enabled support like it was done in previous releases

Other improvements

• Support for OS X (>= 10.10) added
• Enabled print support
• Integrations for qmake, cmake, and pkg-config are now installed
• Documentation in HTML and QCH formats is now generated and installed

Prominent bug fixes

• Fixed missing text rendering on some sites
• Fixed copying to clipboard from web views
• Fixed some ABI compatibility issues
