cmake creates a consistent uri structure in the build directory.
We use that as import path, but when we find a type in them we should
refer back to the original file, as editing those is dangerous because
any edit are lost with the next build.
To find the original file we use the qrc, as the qrc path is mostly
the same of as the uri path.
It is possible to add prefixes which would make an exact match fail,
so we compare the paths from the right to the left and find the
longest match.
To acheive this:
* QrcParser keeps a reversedResources, so the match from right can be
done efficiently, and provides a longestReverseMatches method
* the model manager keeps a list of all common prefixes of the
application paths (build directories), and identify all files in
build directories
* the method fileToSource identifies the files in the build directory
and tries to find the corresponding source file, warning if he
cannot find it
* fileToSource is used for follow Symbol and find usages
We could use fileToSource much more aggressively, to use to in editor
content for the files in the build directory, increasing the
consistency, but that is a more dangerous change for later.
