#32 Preferences

Originally at 2014-10-31T01:35:06Z by Sebastian Sastre closed at 2014-11-01T00:09:30Z (pull request) With this, we have and use two preferences: 1. `helios.browser.showDocOnOpen` and 2. `helios.confirmOnClose` The default values are taken from previous versions. `helios.confirmOnClose` has no UI but if user evaluates in workspace: `SmalltalkSettings at: #helios.confirmOnClose put: false` Helios will close without dialogs (and will as the usual confirm if that one stays true).
