v1.7.0 - Project files and variable descriptions

Another usability release, this one contains the ability to save and load projects.
The previous release introduced the concept of restoring the list of resources and mod directory, now this selection can also be stored as a dedicated project file of type .hacked-project.

As long as the current selection is not stored as a dedicated file, the state will be stored centrally. Otherwise, the central settings file stores a reference to the last project. See also Restore Editor on Load.

Furthermore, as a first showcase, the project files now also support storing meta-information of variables, which can be edited in the Archive window! See Variables for further details.

Finally a minor change also allows for manually entering values for slider-based controls. See here for details.
