Upgraded the system such that it should work in combination with the new core. Notice, please copy the unzipped file into your "/p5.webapp/modules/" folder. This is a change from previous versions. Also make sure you rename the unzipped folder, such that it's named only "system42", without any versioning numbers, etc.
Also realize, that System42 will completely override the default P5 "micro web operating system" desktop, and its logic, in regards to URL resolving, etc. The system is not intended for production sites, but simply as a minimalistic use-case, and testing grounds, as you learn P5, and realise its powers.
Changed the name of the startup file to "startup.hl", to reflect the new startup loader logic in Phosphorus Five.
Besides from this tiny change, please check out the main Zen release for its full feature list.
