Help: Add litehtml based viewer backend

Browse Source

For CMake add litehtml installation path to CMAKE_PREFIX_PATH
For qmake pass litehtml installation path via LITEHTML_INSTALL_DIR qmake
variable

Release build of litehtml is recommended.

The litehtml backend is used by default when available, you can force
QTextBrowser again with the environment variable
"QTC_HELPVIEWER_BACKEND=textbrowser".

Some things are not implemented yet:
- Text search
- Context menu
- Shift-drag to extend existing selection
