Today was a big day in my rack planner's development. A very big day. Today's the day we went multi-format. The planner can now handle Buchla and Synthesizers.com modules as well as Eurorack - in the same plan. Other formats should present few challenges - just a matter of inputting the dimensions of a standard width panel for each. I'm really pleased with how well this has worked out.
Please ignore the nonsense patch - it's purely a test to make sure that all the previously coded functionality works with the new rack sizes.
Also added today were proper load and save routines (before it just loaded and saved a single hard-coded file as a proof of concept) and autoloading of a default rack (rack.xml as per Doug's planner) if found.
