\class FileInProjectFinder
Helper class to find the 'original' file in the project directory for a given file path.
Often files are copied in the build + deploy process. findFile() searches for an existing file
in the project directory for a given file path:
E.g. following file paths:
C:/app-build-desktop/qml/app/main.qml (shadow build directory)
C:/Private/e3026d63/qml/app/main.qml (Application data folder on Symbian device)
/Users/x/app-build-desktop/App.app/Contents/Resources/qml/App/main.qml (folder on Mac OS X)
should all be mapped to
$PROJECTDIR/qml/app/main.qml

checked for existence. This continues until either the file is found, or the relative path
does not contain any directories any more: In this case the originalPath is returned.
