This change checks all paths in the ProjectSettings file for relativity and makes them relative to the location of the
ProjectSettings file if necessary. The paths are also correctly saved relative to the file.
This change adds the node NODE_FILE to the graph and the edge EDGE_INCLUDE, which determine the dependencies between
files by parsing the include preprocessor directive. File nodes can be searched and displayed in the GraphView as file
dependency graph. The filter "file" allows for selecting all files. The file depency information is used on project
refresh do determine which files need to get reparsed.
* added FileManager that keeps track of the files analyzed by the project. It therefore checks if files get added, updated or deleted from the source- and include folders.
* refactored ASTVisitor::hasValidLocation() and implemented one version that search for the location in the currently parsed file and one that searches in all the project's source files.
* quickfix: switched order in FileManager so that header files are parsed first.
* created folder for helper classes used in tests.
* added test code for FileManager
* adjusted test code for Parser Tests.
